摘要
讨论了SAR的基本信号模型,针对这一模型提出了应用匹配傅里叶变换估计SAR多普勒参数的新方法。文中给出了理论分析和仿真,并用机载SAR回波实际数据进行了多普勒参数估计,根据估计的多普勒参数给出了成像结果,表明了该方法可对SAR数据进行盲处理估计出多普勒参数,且精度高。
The basic signal model of SAB is discussed. According to the model, a new method of Doppler Pararneter Estimation for SAR is proposed. At the same time, theoretical analyses and simulation results are given. In addition, we give the Doppler Parameter Estimation using the airborne SAR experimental echo data. In the end, the image of the SAR for the estimated Doppler parameter is obtained. The simulation results and the images prove that the method can make blind processing for SAR data and can efficiently estimate Doppler Parameter, and show that the precision of estimation is high.
