| 摘 要： | 该文总结了弹道导弹目标雷达识别的研究现状，引入微进动和微RCS的概念，推导了进动锥体目标对雷达波的姿态角计算公式，分析了微RCS和姿态角的关系，使用进动锥体目标的微RCS序列估计目标进动参数和惯量比。以惯量比为特征，提出了识别弹头和诱饵的方法。最后给出了仿真结果。

| Abstract: | In this paper, the development of radar identification of ballistic missile warhead is summarized. Conceptions of micro-precession and micro-RCS are introduced. The aspect angle expression of a precession target is derived, and the relationship between micro-RCS and aspect angle is analyzed. Then the precession parameters and inertia ratio are estimated with micro-RCS. Inertia ratio is then used to discriminate warheads and decoys. Finally, a simulation result is provided. |
