This dissertation includes the following parts : 1 . based on the facet model , a method of the simulating of spaceborne sar raw target dates with random distribution is proposed . the simulating algorithm is given and the results are analyzed
本文对星载sar原始回波数据模拟方法进行了研究,主要内容包括: 1 .基于小平面单元模型,给出了一种模拟满足随机分布特性的星载sar目标原始数据的方法。
A time domain method of the simulating sar raw target signals is presented firstly , which can simulate accurately raw dates but burdens upper computational complexity . therefore , a frequency domain method with lower computational complexity is also proposed
因此,又给出了一种频域回波信号生成算法,该方法能够在满足一定条件下利用二维fft算法快速产生分布目标的回波信号,具有较高的计算效率。
