中文摘要：
分析了调频连续波逆合成孔径雷达（FMCW—ISAR）的回波信号特性，讨论了脉冲持续时间内目标连续运动引起的多普勒频移对成像的影响，推导出导致一维距离像主瓣展宽和走动的相位因子，并进一步研究了该相位因子对基于调频连续波逆合成孔径雷达的目标微多普勒特征的影响，在此基础上讨论了调频连续波逆合成孔径雷达目标微多普勒特征与脉冲式逆合成孔径雷达目标微多普勒特征的主要区别。最后的仿真试验验证了理论分析的正确性。
英文摘要：
The characteristics of the echoed signal transmitted by FMCW-ISAR are analyzed. The in- fluence of the Doppler-frequency shift impacted by the target＇ s continuous mov duration is discussed and the phase coefficient which results in the main lobe the range profile is obtained. Then features based on the FMCW-ISAR the pulsed ISAR and FMCW-ISAR ing wid inner-pulse time ening and deviation of the influence of the phase coefficient on the micro-Doppler （m-D） is studied and the main differences of the m-D characteristics between are discussed. The simulation experiment has verified the validity of the theoretical conclusions.
