| 摘 要： | 调频连续波(FM-CW)合成孔径雷达因其体积小、重量轻、低成本及分辨率高等特点越来越受到关注。该文详细推导了调频连续波(FM-CW)体制下去调频FM-CW SAR信号模型，对FM-CW SAR 的特有问题如RVP，斜置，距离走动现象进行了深入研究，提出了改进的去调频FM-CW SAR的距离-多普勒成像算法。通过理论推导及仿真实验，验证了模型和算法的可行性与正确性。

| Abstract: | There is a growing interest in the Frequency Modulated Continuous Wave (FM-CW) SAR for its small cubage,light weight,cost-effective and high resolution.In this paper,the principle of the de-chirped FM-CW SAR is analyzed in detail,the phenomena,for example,Residual Visual Phase (RVP),Slope,range walk are discussed deeply,and the improved range Doppler imaging algorithm for the de-chirped FM-CW SAR is presented.The deduction and the simulation prove the algorithm is feasible and correct. |

| Keywords: | SAR FM-CW Range-Doppler imaging algorithm Residual Visual Phase(RVP) Slope |
