分析了逆合成孔径雷达多目标成像机理和时频分析成像算法,以多弹头的刚性多目标模型为基础,利用时频分析方法对多目标成像进行仿真。并且对距离−多普勒算法和3种逆合成孔径雷达多目标成像时频分析算法进行了比较,结果证明逆合成孔径雷达在多目标成像及识别中的可行性。This article discusses in detail the character of Inverse Synthetic Aperture Radar (ISAR) multi-target imaging techniques and time-frequency algorithms. Based on the model of rigidity multi-target of multiple ballistic missiles, time-frequency analysis technology is proposed to simulate imaging of multiple targets. Also, Range-Doppler (RD) and three ISAR time-frequency algorithms for multi-targets imaging are compared. The result is given to prove the feasibility of ISAR imaging and recognition of multiple targets.
