摘　　要：获取空间高速动态目标的宽带回波数据是进行空间目标电磁特性研究,开展空间目标探测与识别的基础。针对静态测量和动态测量不同形式的雷达发射信号,分别建立了空间目标静态测量条件下扫频宽带回波信号模型和解线频调的高速宽带回波信号模型。在分析两种信号模型差异的基础上,提出了一种利用静态数据仿真生成高速动态目标宽带回波的方法,并详细分析了该方法的适用条件。最后对仿真方法进行了验证,证明了其可行性和正确性。Obtaining radar echo of high-speed dynamic space target is the basis of research on space targets＇ electromagnetic characteristics, space targets exploration and recognition. Swept wideband echo model under static measurement and LFM echo model under dynamic measurement were established, according to the diverse signal transmitted in static measurement and dynamic measurement. The method for simulating the LFM signal＇s echo of high-speed dynamic targets after dechirp using static measured data were studied based on the detailed analysis about the difference between above two signal model The applicability of the proposed simulating method was analyzed in detail. The result based on real measured data shows the validity of the simulation method present.
