【摘要】：針對地球同步軌道衛(wèi)星發(fā)射-低軌道衛(wèi)星接收的新體制雙站合成孔徑雷達(dá)(geosynchronous-earthorbit-low-earth-orbit bistatic synthetic aperture radar,GEO-LEO BiSAR)具有收發(fā)平臺軌道差異大、空間大尺度異構(gòu)等特點(diǎn),對地面分辨特性和軌道構(gòu)型進(jìn)行了分析。文中從收發(fā)平臺的空間幾何關(guān)系出發(fā),深入分析了地面二維分辨率和分辨率方向角等性能,給出在不同觀測模式下的構(gòu)型約束規(guī)律,并規(guī)劃了軌道構(gòu)型設(shè)計(jì)方案。仿真實(shí)驗(yàn)結(jié)果驗(yàn)證了理論分析的正確性。
[Abstract]:A novel bistatic synthetic Aperture Radar (bistatic synthetic Aperture Radar) for geosynchronous Satellite launch and low orbit Satellite reception. Geosynchronous-earthorbit-low-earth-orbit bistatic synthetic aperture. Radar. GEO-LEO BiSAR) has the characteristics of large orbit difference of transceiver platform, large scale heterogeneity of space and so on. The ground resolution characteristics and orbit configuration are analyzed. Based on the spatial geometric relationship of the transceiver platform, the performance of the ground two-dimensional resolution and the resolution direction angle are analyzed in depth. The configuration constraint law under different observation modes is given and the design scheme of orbit configuration is planned. The simulation results verify the correctness of the theoretical analysis.
