高分辨率合成孔径雷达（SAR）动目标显示与成像系统的性能可以通过对整个成像系统进行仿真建模来分析和评估。在时域中的原始数据生成实现了一个现实的仿真过程，提供了计算复杂度可以容忍。在这封信中，我们提出了一个有效的SAR原始数据生成器的场景，包括静态和运动目标。扩展场景和运动目标的原始数据集分别在频域模拟，并在时域叠加。生成的固定和移动目标的原始数据也被处理和分析。
The performance of the high-resolution synthetic aperture radar (SAR) with moving-target indication and imaging systems can be analyzed and evaluated by modeling the whole imaging system through a simulation. The raw-data generation in the time domain achieves a realistic simulation procedure provided that computational complexity can be tolerable. In this letter, we proposed an efficient SAR raw-data generator of a scene that includes both static and moving targets. The raw data set of an extended scene and the moving target is simulated in the frequency domain separately and superposed in the time domain. The generated raw data for fixed and moving targets are also processed and analyzed.
