摘　　要：为精确研究自旋条件下弹载雷达回波信号的关键参数,建立弹头自旋再入的运动模型,推导出任意角度波束微元回波延时、多普勒频率和回波功率等参数的数学公式,最后通过仿真验证了模型和公式的正确性。所得结论对自旋条件下宽波束弹载雷达回波的精确模拟具有很强的借鉴参考意义。In order to simulate accurately the key parameters of echo signals for missile-borne radar under the condition of spinning, the paper sets up a spinning model during warheads’ re-entry, and deduces the mathematical expressions of such parameters as time-delay, Doppler frequency and echo power of the beam infinitesimal at a random angle. Finally, the correctness of the model and expressions is proved through simulation. The conclusion of the paper has an important referential significance for the accurate simulation of wide-beam radar echo in the future.
