摘　　要：为解决导弹自旋运动模型建模复杂、计算量大的问题,建立了一种新的导弹自旋运动模型.以此模型为基础,计算分析得到雷达照射区域的变化规律.采用网格映像法划分雷达照射区域,建立雷达回波模型,并对雷达多脉冲的回波进行仿真.结果表明:雷达多脉冲回波会受到多普勒频率的调制而表现出多个周期,回波的频谱可验证所建模型准确.In order to solve the problems of complex modeling and heavy computation burden of missile spin motion model,a new missile spin motion model was established in this paper.Based on this model,the variation law of radar irradiation area was got.Then,the radar echo model was established by dividing the radar irradiation area with grid image method.The simulation results showed that the radar multi-pulse echo is modulated by Doppler frequency and shows multiple cycles.And the spectrum of the echo verified the accuracy of the model and conclusion..
