星载合成孔径雷达回波数据仿真研究

Study on Simulation of the Spaceborne Synthetic Aperture Radar Echo Data

本文对星载合成孔径雷达(SAR)图像仿真方法进行了研究,在分析并建立合成孔径雷达回波信号数学模型的基础上,提出了基于分布目标的SAR回波信号数据仿真,进而提出了一种与传统实现方法不同的SAR原始回波数据的生成方法,并用这种方法进行了初步的建模和仿真,验证了其有效性。

This paper studies ＂the imagery simulation methods of the spaceborne synthetic aperture radar＂. Based on the analysis, ＂ the echo data mathematic model＂ is built, the unthors author then propose ＂ the method of echo data simulation based on the stochastic distributed target＂, based on which the authors further set forth a method of creating raw data different from the conventional one, whose availability is validated by modeling and simulating.
