对合成孔径雷达(SAR)卫星的侦察可以为合成孔径雷达电子战提供有力的支援。在地基侦收站跟踪侦察SAR卫星的背景下,建立了SAR卫星地基侦察模型,该模型利用真实卫星的天线参数及轨道参数,在空间几何模型基础上,获得不同工作模式下方位向的天线增益,并采用插值算法进行处理获得距离向天线增益,通过仿真分析SAR卫星地基侦察信号,为SAR卫星参数估计及工作模式识别等研究奠定了基础。
Reconnaissance of Synthetic Aperture Radar (SAR) satellites can provide strong support for synthetic aperture radar electronic warfare. In the background of the reconnaissance SAR satellite, the SAR satellite ground reconnaissance model was set up. Based on the space geometry model, the antenna gain of the azimuth in different working modes was obtained by using the parameters of the real satellite and the orbital parameters. , And processed by interpolation algorithm to obtain the antenna gain from the distance. By analyzing the SAR satellite ground reconnaissance signals through simulation, the research laid the foundation for SAR satellite parameter estimation and working pattern recognition.
