| 摘 要： | 主要研究了极化SAR对直线运动目标的成像仿真，并对成像结果进行时频分析。根据极化SAR工作原理，推导并建立交替发射同时接收体制下的运动目标回波模型，利用R—D成像算法分别对匀速运动目标、匀加速运动目标进行了仿真。最后利用Wigner-Ville分布对仿真结果进行分析，验证了该仿真模型的正确性。

| Abstract: | Image simulation of linear moving target according to PolSAR is studied mainly. And the imaging result is dealt with by time-frequency analysis. According to polarization SAR principle, return signal mathematic model of moving target are derived and established under alternate-send and simultaneous-receive mechanism. The computer simulation of constant target and accelerated target imaging using the R-D imaging algorithm is presented. At last the result of simulation is analyzed by Wigner-Ville distribution, proving the correctness of analysis in theory. |
