Geo Sar(지오 사르)란 무엇입니까?
Geo Sar 지오 사르 - Geosynchronous SAR (GEO SAR) is an active research area because it provides significant new capability, especially its much-improved temporal sampling. [1] The error caused by terrain elevation under the LEO SAR is negligible, and in GEO SAR the error will cause serious azimuth defocusing. [2] It is found that the Doppler spectrum is generally aliased in GEO BiSAR regarding the low pulse repetition frequency (PRF) adopted by the GEO SAR. [3] GEO SAR has great potential in marine surveillance. [4] Geosynchronous SAR tomography (GEO TomoSAR) is a technique that combines geosynchronous SAR (GEO SAR) with SAR tomography.

Geosynchronous Synthetic Aperture Radar (GEO SAR) has advantages of a short revisit time and large coverage for the scene of interest, so lots of theories and analysis toward the GEO SAR have been developed. [1] Due to the high altitude of geosynchronous synthetic aperture radar (GEO SAR), its synthetic aperture time can reach up to several hundred seconds, and its revisit cycle is very short, which makes it of great application worth in the remote sensing field, such as in disaster monitoring and vegetation measurements. [2] Due to geosynchronous synthetic aperture radar’s (GEO SAR) high orbit and low relative speed, the integration time reaches up to hundreds of seconds for a fine resolution. [3] Multiple-input multiple-output geosynchronous synthetic aperture radar (MIMO GEO SAR), composed by several mini-satellites in GEO orbits, has more spatial degrees of freedom, which helps to suppress clutter and improves the performance of ground moving target indication (GMTI). [4] The Geosynchronous Synthetic Aperture Radar (GEO SAR) has a long synthetic aperture time. [5] The trajectory for the geosynchronous synthetic aperture radar (GEO SAR) is complicated and the ship target moving combines not only translational motion but also 3-D rotate with the different state of the sea, the echo simulation of ship target in the unified coordinate system be-come a vital problem. [6] Faraday rotation (FR) is the rotation of the polarization plane relative to the incident wave under the influence of the ionosphere when the signal passes through the ionosphere, which will affect Geosynchronous Synthetic Aperture Radar (GEO SAR) imaging. [7] Geosynchronous synthetic aperture radar (GEO SAR) is more challenging to process than the classical synthetic aperture radar (SAR) because the flight geometry is more complicated and the data is usually non-stationary. [8] The geosynchronous synthetic aperture radar (GEO SAR) echo simulation has an important significance for GEO SAR system design and image algorithm verification. [9] The sub-satellite track of geosynchronous synthetic aperture radar (GEO SAR) presents the figure “8” or “O”, which causes the great changes of platform motion direction and the different projection of anisotropic irregularities along the line-of-sight (LOS) direction. [10] Due to high orbit and low relative speed, the integration time of geosynchronous synthetic aperture radar (GEO SAR) for a fine resolution reaches up to hundreds of seconds. [11] Geosynchronous synthetic aperture radar (GEO SAR) has the characteristics of wide coverage and short revisit time, which makes GEO SAR moving target indication more valuable than other platforms. [12] Geosynchronous synthetic aperture radar (GEO SAR) has the potential for conducting long-term observation of target zones, which is essential for remote sensing applications such as disaster monitoring and vegetation measurements. [13] Geosynchronous synthetic aperture radar (GEO SAR) has great potentials in synthetic aperture radar ground moving target indication (SAR-GMTI) due to its high time resolution and wide swath coverage. [14] A geosynchronous synthetic aperture radar (GEO SAR) can achieve a shorter revisit time, a longer observation time, and a larger coverage area for the target scene compared with low earth orbit (LEO) SARs. [15] Geosynchronous synthetic aperture radar (GEO SAR) is a very remarkable tool for monitoring rapid geologic disasters due to its short revisit time and long coverage time for targets. [16] Due to the high orbital altitude, the large-area antenna and solar array will be utilised in geosynchronous synthetic aperture radar (GEO SAR) to meet the requirement of high transmitting power. [17] Compared to the monostatic geosynchronous synthetic aperture radar (GEO SAR), GEO bistatic SAR can provide finer spatial resolution and higher signal-to-noise ratio (SNR) with lower system complexity, which leads the GEO-LEO (low earth orbit) SAR be a hot research topic. [18] Geosynchronous synthetic aperture radar (GEO SAR) can provide daily repeat-pass and high coherent image pairs for interferometry. [19] Nevertheless, this issue has not been addressed yet in the geosynchronous synthetic aperture radar (GEO SAR) situation.
