摘要: 該文研究發(fā)射機(jī)固定的雙站合成孔徑雷達(dá)(雙站SAR)的運(yùn)動(dòng)目標(biāo)成像問題,應(yīng)用WVD Radon變換來估計(jì)運(yùn)動(dòng)目標(biāo)回波的多普勒參數(shù)，以此來調(diào)節(jié)成像和運(yùn)動(dòng)補(bǔ)償處理參數(shù)，得到較好的運(yùn)動(dòng)目標(biāo)成像效果。計(jì)箅機(jī)仿真結(jié)果證明該文推導(dǎo)的正確性。

Abstract: This paper studies the imaging of moving target in the situation of the bistatic synthetic aperture radar with stationary transmitter. The WVD-Radon method is used to estimate the Doppler frequency parameter of the moving target, and to adjust the parameter of the imaging and the motion compensation to get better imaging result. The results of computer simulation are given to demonstrate that the conclusion of the paper is correct. -
