SARDopplerEstimation
从回波中估计多普勒参数是合成孔径雷达运动补偿的关键。文中研究了多目标回波对参数估计的影响，从理论上推导了估计多普勒中心和调频率对回波的不同要求，并用两个指标举例分析了一段实测机载SAR数据，给出了实际应用中参数估计时选择回波的原则。(Doppler parameters estimation from radar echoes is a key step in SAR(Synthetic Aperture Radar}motion cornpensation．
This paper researched the efect of multiple targets echoes to estimate parameters and deducted theoretically the different
requirement for echoes in estimating doppler centroid and doppler frequency modulation rate．Th en giving a real airborne SAR echo
as example，we analyzed it with two measurements and concluded the principle about choosing echoes in practice．)
