Scanning Range 扫描范围 - The full-wave simulation results for the proposed configurations in 2-D phased arrays provide a reduction in the number of PSs of until 69% for a scanning range of ±25° in elevation and ±40° in azimuth. [1] The proposed FSS has a good angle stability and polarization stability in a scanning range up to 60°. [2] When the gantry was tilted and the orbit was completely out of the scanning range, the rate of reduction was 47. [3] 5mm2 with the prototype system, which could be further extended easily and is limited only by the size of the line-scanning imaging sensor and the scanning range of the motor. [4] 15 V (scanning range: 0–1. [5] 1 m scanning range. [6] 4dBi), and the scanning range is ±30°. [7] At an actuator frequency between 40 Hz and 100 Hz the scanning range is up to 2 mm. [8] 5 dB gain enhancement in the scanning range of ±43° has been achieved with the aperture efficiency of 98%, the low profile of 1. [9] They all underwent CT plain scan and MR-DWI scan with same scanning range, layer thickness (4 mm) and interlayer spacing (4 mm) (The time interval between two examinations: less than 4 h). [10] 3 dBi, the scanning range reaches ±45° in both horizontal and vertical planes. [11] We demonstrate theoretically and experimentally that by expanding the design space, the proposed designs outperform previous designs in terms of scanning range and fill factor. [12] 43dB maximum gain, good axial radio performance and scanning range from 0 to 60, the array provides superb performance for satellite communication systems. [13] The simulated and measured beams show good agreement in terms of scanning range and radiation performance. [14] The simulated and measured results show that the proposed low-profile planar PAA-EC operates in the 8-12 GHz band with ±45° scanning range. [15] Finally, the scanning range of 46°×12° is realized in the wavelength range of 1500 nm to 1600 nm. [16] The simulated results give a maximum gain of 30 dB and a scanning range of 20° in both planes φ = 0° and φ=90°. [17] The method is based on the induced reconstruction matrix, thereby estimating the pattern of any beam position within the scanning range. [18] 9 GHz and the scanning range of ±30°, the gains are higher than 16 dBi, and the SLLs are lower than −8 dB. [19] Another problematic situation is the case that the target object is large so that the scanning range exceeds the unambiguous range. [20] However, it cannot avoid the对于所提出的二维相控阵配置的全波仿真结果,对于仰角 ±25° 和方位角 ±40° 的扫描范围,PS 的数量减少了 69%。 [1] 所提出的FSS在高达60°的扫描范围内具有良好的角度稳定性和偏振稳定性。 [2] 当机架倾斜且轨道完全超出扫描范围时,减少率为 47。 [3] 5mm2的原型系统,可以很容易地进一步扩展,仅受线扫描成像传感器尺寸和电机扫描范围的限制。 [4] 15 V(扫描范围:0-1。 [5] 1 m 扫描范围。 [6] 4dBi),扫描范围为±30°。 [7] 在 40 Hz 和 100 Hz 之间的执行器频率下,扫描范围可达 2 mm。 [8] 在 ±43° 的扫描范围内实现了 5 dB 的增益增强,孔径效率为 98%,低剖面为 1。 [9] 均接受CT平扫和MR-DWI扫描,扫描范围、层厚(4 mm)、层间距(4 mm)相同(两次检查时间间隔:小于4 h)。 [10] 3 dBi,扫描范围在水平和垂直平面上都达到±45°。 [11] 我们从理论上和实验上证明,通过扩展设计空间,所提出的设计在扫描范围和填充因子方面优于以前的设计。 [12] 43dB的最大增益、良好的轴向无线电性能和从0到60的扫描范围,该阵列为卫星通信系统提供了卓越的性能。 [13] 模拟和测量的光束在扫描范围和辐射性能方面表现出良好的一致性。 [14] 仿真和测量结果表明,所提出的薄型平面 PAA-EC 工作在 8-12 GHz 频段,扫描范围为 ±45°。 [15] 最终在1500nm~1600nm的波长范围内实现了46°×12°的扫描范围。 [16] 仿真结果给出了 30 dB 的最大增益和 20° 的扫描范围,在两个平面 φ = 0° 和 φ=90°。 [17] 该方法基于诱导重建矩阵,从而估计扫描范围内任何光束位置的模式。 [18] 9 GHz,扫描范围±30°,增益高于16 dBi,SLL低于-8 dB。 [19] 另一个问题的情况是目标物体很大以致扫描范围超过明确范围的情况。 [20] 但是,它无法避免 <inline-formula> <tex-math notation="LaTeX">$n = -2$ </tex-math></inline-formula> 空间谐波,这会导致另一个限制扫描的阻带范围在前象限。 [21] 所提出的阵列实现了 40% 的带宽(8-12 GHz),同时在 E 平面上覆盖了 ±65° 的扫描范围(VSWR < 2. [22] 将开放格式标准镶嵌语言 (STL) 数据集(1 个来自高精度牙科实验室扫描仪的参考文件、10 个来自口内扫描仪的文件和 10 个来自室温下数字化常规印模的文件)导入计量软件程序,以及模拟不同的临床情况,确定了 5 组扫描范围(AB、FGH、CDEF、BCDEFG 和 ABCDEFGH)。 [23] 通过具有扩大视场 (FOV) 的新光学系统设计和具有增加的 z 扫描范围和速度的新型微可调透镜实现了提高的细胞产量,从而实现了多个交错平面的快速稳定成像。作为 3D 功能成像。 [24] 该阵列能够在±45°的扫描范围内在一个平面上同时辐射两个或多个聚焦光束;这些光束可以随意重新配置。 [25] “悦春”是一款交互式投影系统,利用扫描测距仪跟踪手部位置,并通过图形操作提供感官反馈,营造艺术情境。 [26] 5∘扫描范围与2。 [27] 在E面,由于端口阻抗和WWCIM层在70°扫描范围内的变化很小,端口阻抗很容易匹配。 [28] ,代码),光束方向,扫描范围,增益和 SLL 在不改变阵列布局的情况下改变。 [29] 扫描范围从颅尖延伸至枕骨大孔。 [30] 可实现 17 dBic 的实测峰值增益和大于 83° 的波束扫描范围,并具有良好的 CP 性能。 [31] 我们讨论了每个类别中的示例,并比较了它们的性能指标,包括孔径效率、增益、带宽以及扫描范围和分辨率。 [32] 然而,大多数现有的商业 AFM 提供的扫描范围小于几个 100 μm。 [33] 与常规方法相比,同步辐射X射线衍射具有更好的分辨率、致密性和扫描范围。 [34] 方位角和仰角可以达到±60°的扫描范围。 [35] 通过傅里叶变换红外光谱分析鉴定了关键官能团,并在 Ibn Sina State Company (ISSC) 的 KBr disc 的 Shimadzu (FT-IR-8300S) 分光光度计上在室温下 400-4000 cm -1 的扫描范围内记录。 [36] 在单个端口的激励下,即<inline-formula><tex-math notation="LaTeX">$P_{1}$</tex-math></inline-formula>,扫描范围从<inline -formula><tex-math notation="LaTeX">$14^{\circ }$</tex-math></inline-formula> 到 <inline-formula><tex-math notation="LaTeX">$51^ {\circ }$</tex-math></inline-formula>,旁瓣电平 (SLL) 低于 -20 dB。 [37] 科睿唯安生成的 WoS 数据库中的文献计量数据扫描范围涵盖 1975 年至 2020 年 3 月之间的日期。 [38] 数据,例如体积计算机断层扫描剂量指数 (CTDIvol) 值、扫描范围、剂量长度乘积 (DLP) 值以及基于前后 (AP) 和横向 (LAT) 的患者头部直径以标准化的方式记录表格进行分析。 [39] 结果表明,所提出的相控阵可以实现-60~60°的扫描范围,带内效率大于77%,有望在未来的无线能量传输系统中得到应用。 [40] 所研究的可重构 LWA 因其紧凑、易于实施、相当高的增益和相对较宽的光束扫描范围而适用于光束扫描应用,这将通过本综合审查得到证明。 [41] 仿真结果表明,在110 m处,水平和垂直方向的扫描范围分别为360°和±14∘,角分辨率为0。 [42] 实验测试证实了理论预测,验证了分析工具,并显示在 15% 带宽内所有扫描平面的扫描范围为 70°。 [43] 7 dBi 和 ±21° 的扫描范围,最大馈电隔离为 24 dB。 [44] 4mm,测量扫描范围800×1000×600mm(长×宽×深)。 [45] 分析物由二极管测定检测器 (DAD) 在 210 nm 至 400 nm 的扫描范围内检测。 [46] 扫描变容二极管的电容会导致 16° 的光束扫描范围,峰值实现增益为 8。 [47] 30分钟内产生的信号在0-40GHz之间功率波动不超过3dB,扫描范围波动600MHz左右。 [48] 采用弱耦合多芯光纤的光子集成电路的光束调节器可在 24 GHz 射频频带和 59° 扫描范围内实现 3 GHz 带宽,从而实现 16QAM 12 Gbps。 [49] 在日本的 18F-氟脱氧葡萄糖 (18F-FDG) 肿瘤 PET/CT 中,扫描范围、校正方法的可用性以及延迟扫描的决定尚不清楚。 [50]

Beam Scanning Range
4 GHz with a beam scanning range from −71◦ to +31◦. [1] This antenna array shows advantages in terms of low complexity, high XPD, high aperture efficiency and wide beam scanning range. [2] A beam scanning range of approximately 27° is achieved over frequencies from 58. [3] The measured patterns show near ideal patterns with a wide beam scanning range of ±70° (V- and H-pol) and a high cross-polarization rejection of 27 dB. [4] By using discrete antenna sources separately distributed at different locations, the proposed lens antenna achieves a wide beam scanning range about ± 33° with a gain ripple of 4. [5] The fully functional prototype demonstrates a foreside beam scanning range of ± 40° with a system gain of 20. [6] The operating frequency range is 325–400 GHz and the beam scanning range is 22. [7] Match stubs close to the radiation slots are utilized to suppress the open stopband, which help enlarge the beam scanning range. [8] Because of its small antenna length, wide beam scanning range, and high gain, the antenna can be widely used in wireless communication or radar systems. [9] The simulated results clearly illustrate a dynamic beam scanning range of 45° through the use of an external bias voltage ranging between 0 and 40 V. [10] A wide beam scanning range of ± 20°in H-plane covering frequency form 91. [11] And the beam scanning range of the antenna reaches±35°. [12] 72 dB, beam scanning range of ±40°, and mutual capacitance change ratio >4. [13] A sparse antenna array can relieve the channel area restriction at the cost of possible grating lobes or a narrower beam scanning range. [14] The presented antenna yields a wide S11 bandwidth (BW), high gain and wide beam scanning range as required for broadband mobile applications. [15] 5~\lambda _{0}$ element space has the beam scanning range of ±43 ° at the endfire direction and the gain of higher than 7. [16] The antenna proposed here comprises 15 matched unit cells with high directivity which provides a backward to forward beam scanning range of 80° with frequency from 24. [17] With the integration of 8×16 phased array antenna, the devised ILA exceeds the conventional beam scanning limitations by 93%, achieving a main beam scanning range of 174 and scan loss of 2. [18] It is concluded that helix elements, when used as an array, offer significant improvements for wireless power link efficiency, whilst also offering a reasonable beam scanning range. [19] However, the optimization problem which takes into account the coverage radius of the UAV and beam scanning range, is formulated as a non-convex problem and hence is difficult to solve. [20] The beam scanning range of the proposed antenna is 107° within 9–13. [21] Metal shielding vias are introduced to suppress the coupling between the antenna elements operating in different bands, meanwhile, defected ground structure is introduced to eliminate the scan blindness effect and improve the beam scanning range effectively. [22] Results show that, with the one-bit phase shifting resolution, the antenna achieves the beam scanning range from -30 degrees to -10 degrees while the gain reaches up to more than 20 dB and the axial ratio keeps less than 3 dB. [23] Simulation results show that the antenna can achieve a beam scanning range of 56 degree in the backward side at 16 GHZ. [24] 0 dB sidelobe levels (SLLs), and ±50° beam scanning range could be realized through the proposed TMAPW-MB module. [25] Full wave numerical simulations are conducted, and the results show large beam scanning ranges of the reflectarray over 50° in the plane containing the offset feed and over 40° in the plane perpendicular to the feed plane. [26]4 GHz,波束扫描范围为 -71° 至 +31°。 [1] 该天线阵列在低复杂度、高XPD、高孔径效率和宽波束扫描范围方面显示出优势。 [2] nan [3] nan [4] nan [5] nan [6] nan [7] nan [8] nan [9] nan [10] nan [11] nan [12] nan [13] nan [14] nan [15] nan [16] nan [17] nan [18] nan [19] nan [20] nan [21] nan [22] nan [23] nan [24] nan [25] nan [26]
Wide Scanning Range
In this concept, we use periodic parasitic elements and the generator impedance to control the Active Voltage Standing Wave Ratio (AVSWR) over a wide scanning range. [1] Steering both laser beams and ultrasound waves with a scanner’s mirror immersed in the water, our system achieves a wide scanning range and a high signal-to-noise ratio as well as the B-mode imaging speed of 500 Hz. [2] The measured patterns, in在这个概念中,我们使用周期性寄生元件和发生器阻抗来控制宽扫描范围内的有源电压驻波比 (AVSWR)。 [1] 我们的系统通过浸入水中的扫描仪反射镜控制激光束和超声波,实现了宽扫描范围和高信噪比以及 500 Hz 的 B 模式成像速度。 [2] nan [3] nan [4] nan [5] nan [6] nan [7] nan [8] nan [9]
Large Scanning Range
In this work, we developed a fluorescence and photothermal microscope with extremely large scanning range and high spatial resolution. [1] In the case of the point-to-multipoint link, they have to provide beam reconfigurability over a large scanning range while maintaining a low profile and a limited cost. [2] A 64-channel SiN-Si based one-dimensional (1D) OPA chip has been designed to handle high beam power to achieve large scanning range. [3] 5, respectively, in large scanning range images. [4]在这项工作中,我们开发了一种具有极大扫描范围和高空间分辨率的荧光和光热显微镜。 [1] 在点对多点链路的情况下,它们必须在大扫描范围内提供光束可重构性,同时保持低剖面和有限的成本。 [2] nan [3] nan [4]
Angular Scanning Range
Experimental results show a high main-beam energy ratio, low sidelobe levels, and a wide angular scanning range. [1] A 16-element array is fabricated to validate the design, which experimentally shows a continuous angular scanning range of ±10°around broadside in the band from 16 to 18 GHz, with a peak gain of 18 dBi and a maximum gain drop of 4 dB. [2] Practically significant relationships were obtained and factors that limit the diffraction efficiency and the angular scanning range were determined. [3]实验结果表明,主波束能量比高、旁瓣电平低、角度扫描范围宽。 [1] 制造了一个 16 元素阵列来验证该设计,实验表明在 16 至 18 GHz 频带内围绕宽边的连续角度扫描范围为 ±10°,峰值增益为 18 dBi,最大增益下降为 4 dB . [2] nan [3]
Entire Scanning Range
However, the fulfillment of the desired high gain constraints over the entire scanning range is still a challenging issue. [1] An axial ratio (AR) < 3 dB is demonstrated over the entire scanning range. [2]然而,在整个扫描范围内实现所需的高增益约束仍然是一个具有挑战性的问题。 [1] nan [2]
Larger Scanning Range
Compared with the conventional approaches, our approach could obtain higher CPI while being available for a larger scanning range. [1] We improve hinge design of WIMSM for larger scanning range. [2]与传统方法相比,我们的方法可以获得更高的 CPI,同时可用于更大的扫描范围。 [1] 我们改进了 WIMSM 的铰链设计以实现更大的扫描范围。 [2]
Limited Scanning Range
At present, mobile robots equipped with a single sensor in an indoor environment suffer from insufficient mapping accuracy and limited scanning range. [1] The experimental results show that our method can effectively overcome the adverse effects of sparse-view conditions and a limited scanning range. [2]目前,在室内环境中配备单个传感器的移动机器人存在测绘精度不足和扫描范围有限的问题。 [1] 实验结果表明,我们的方法可以有效克服稀疏视图条件和有限扫描范围的不利影响。 [2]
Total Scanning Range
A larger lens can improve the resolution by reducing the beam spacing but at the cost of a smaller total scanning range. [1] AR of the main lobe is less than 2 dB in the total scanning range. [2]较大的透镜可以通过减小光束间距来提高分辨率,但代价是总扫描范围较小。 [1] 在整个扫描范围内,主瓣的 AR 小于 2 dB。 [2]
Overall Scanning Range
The antenna has an overall scanning range of 268°, −10 dB impedance BW of 15. [1] Next, the ability to control the pointing direction of the refocused beam with high precision over a narrow angular range is demonstrated, though the challenge of increasing the overall scanning range of the refocused beam remains. [2]该天线的总扫描范围为 268°,-10 dB 阻抗 BW 为 15。 [1] 接下来,展示了在窄角度范围内高精度控制重聚焦光束指向方向的能力,尽管增加重聚焦光束的整体扫描范围仍然存在挑战。 [2]
Frequency Scanning Range
This simple method for stable frequency shifting can be used in atomic or molecular physics experiments that require a laser frequency scanning range on the order of several GHz. [1] We present and investigate a scheme for the error estimation formula derivation of Brillouin frequency shift (BFS) extraction based on an optimized neural network and frequency scanning range for a Brillouin optical time-domain analyzer (BOTDA) system. [2]这种用于稳定频移的简单方法可用于需要数 GHz 量级激光频率扫描范围的原子或分子物理实验。 [1] 我们提出并研究了一种基于布里渊光时域分析仪 (BOTDA) 系统的优化神经网络和频率扫描范围的布里渊频移 (BFS) 提取的误差估计公式推导方案。 [2]
