| 摘 要： | 由于大气干扰的影响,雷达平台很难按照理想轨迹飞行,因此对SAR轨迹偏离下的三维场景回波模拟研究具有现实意义,但此方面在国内研究较少.文中基于SAR轨迹偏离条件下的回波信号模型,提出了适合此模式的SAR回波模拟频域算法,推导了SAR回波频域模拟公式,分析了算法的性能及应用范围,给出了仿真结果和结论,证明了所提算法的有效性和可行性.

| Abstract: | The study of three-dimension scene simulation of raw signal under trajectory deviations is important in practice,because SAR cannot fly without trajectory deviations from the nominal one due to atmospheric turbulence,but there were only few men researching it in China.In this paper,based on the echo model under SAR trajectory deviation,a SAR raw signal frequency-domain simulation method of this mode is brought forward.The formulae of the SAR raw signal frequency-domain simulation are deduced in detail.The c... |
