摘要：

研究了在波浪作用下，海面角反射器干扰的微动建模及其微多普勒特性仿真问题。以船搭载的角反射器干扰为具体研究对象，根据海上目标耐波性理论，结合海况等级和角反射器载体的水动力系数，建立了在各种海情条件下角反射器摇摆运动仿真模型。根据设定的雷达参数，推导了角反射器随载体的横摇和垂荡运动产生的雷达微多普勒模型。最后，采用时频方法提取了角反射器回波的微多普勒特征，通过仿真实验验证了模型的正确性。

Abstract:

A motion model and a micro-Doppler signature generation model for corner reflectors in the sea surface are proposed. Based on the sea keeping theory, considering the sea state and the hydrodynamic coefficient of the carrier, the motion model of the corner reflector is established. According to the radar parameters, the micro-Doppler model of the corner reflectors, due to the roll and heave motion, is derived. Finally, the timefrequency transform is used to analyze the timevarying micro-Doppler features. A number of numerical examples are presented to demonstrate the effectiveness of the proposed model.
