一种面向雷达工作流程的星载合成孔径雷达回波模拟

合成孔径雷达系统模拟是雷达系统设计最有效、最经济的检测方法,它可对雷达的功能、雷达的结果通过计算机进行模拟,改变参数就可获得不同地物、不同雷达参数、不同雷达模式的模拟结果。与设备仿真相比,它能快速实现并且不需高昂的成本。介绍了一种星载合成孔径雷达模拟方法,它以实际雷达信号的流程为依据,模拟雷达各部分的工作,更接近真实的模拟合成孔径雷达的回波。

A Spaceborne Synthetic Aperture Radar Simulator Based on Radar Operation

Synthetic Aperture Radar (SAR) system simulation is the most effective and commercial way to verify the system design. Using the computer, it can simulate the radar functions and results, and by changing the coefficient, it can achieve the result of the different terrain, different radar coefficients and different radar operation modes. Comparing with emulation, it spends little time and cost. In this paper, a spaceborne synthetic aperture radar simulator is presented. It is based on the radar real operation, and simulates some parts of radar system. It is approved that this approach can simulate the SAR image more realistically.
