Abstract

A time domain simulator useful to obtain the pulse response for the generic bistatic SAR configuration is here presented. Moreover, we focus on two particular bistatic systems, i.e. the twin SAR and the space-surface SAR, for which we obtain, under some analytical approximations, the Transfer Functions. Finally, to investigate the possibility to perform an efficient processing in the frequency domain for these two systems, we perform a numerical comparison between the point spread functions, obtained using the time domain simulator and the inverse FFT of the Transfer Functions.
双基地SAR模拟:时域和频域方法
本文介绍了一种时域模拟器,用于获取通用双基地SAR配置的脉冲响应。此外,我们重点讨论了两种特殊的双基地系统,即双基地SAR和空间-地面SAR,在一些解析近似下,我们得到了它们的传递函数。最后,为了研究在频域对这两个系统进行有效处理的可能性,我们对使用时域模拟器获得的点扩展函数和传递函数的逆FFT进行了数值比较。
