为了精确研究自旋条件下弹载脉冲多普勒( PD)雷达的回波信号，本文建立弹头再入自旋运动模型，得到了点波束回波的延时和多普勒频率公式。通过仿真，验证了模型和公式的正确性。所得的结论为宽波束雷达回波精确模拟奠定了坚实的基础，具有很强的借鉴意义。

In order to simulate the echo signals of missile-borne radar under the condition of spin accurately, the paper sets up spin model during warheads re-entry, and obtains the mathematical expressions of time-delay and Doppler frequency for spot-beam. After the simulation, the validity of the model and formula is been proved. The conclusion of the paper sets the strong foundation for the accurate simulation of wide-beam radar echo in the future and has an important reference significance.
