| 摘 要： | 合成孔径雷达平台的飞行航线,一般会受到不稳定因素的影响而产生误差,导致合成孔径雷达成像过程中需要估计运动参数、多普勒参数.文中介绍了非线性CS算法特点、子孔径相关法估计多普勒调频率.根据雷达回波信号模型设计和实现机载SAR回波信号的生成系统,使用模拟产生的大斜视角SAR回波数据进行了多普勒参数估计及运动参数的估计,并使用估计的参数进行了非线性CS算法的成像.

| Abstract: | Because of the motion error of SAR platform caused by unstable factors,the estimation of doppler parameters and motion parameters are necessary in SAR imaging.This paper introduces the NCS algorithm and Map Drift(MD).According to the model of the SAR echo signal,the simulation production system of SAR echo data is designed and realized.Then,through the computer simulation of simulated data,doppler parameters estimation and NCS algorithm are realized. |
