Radar Feature Extraction of Micro-precession Ballistic Missile Warhead
微进动弹道导弹目标雷达特征提取

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.
