摘　　要：弹道目标的微动特性正成为目标识别领域的一个研究热点。建立了弹道目标进动的数学模型,分析了有翼弹头和无翼弹头进动特性对雷达回波调制的差异性,分别进行了有翼弹头进动仿真实验和有翼弹头在微波暗室条件下的微动实验。暗室实验结果证明了仿真结果分析的正确性,同时也证明了进动数学模型的正确性。The micro motion speciality of ballistic targets is becoming a research hotspot in the domain of target recognition. The mathematical model of precession of ballistic missiles is established, the difference between warhead with vanes and warhead with no vanes is analyzed, and the simulation experiment of warhead with vanes precession and micro-motion experiment in darkroom are carried out respectively. The experimental result in darkroom proves that the analysis of simulation result is correct, which also verifies the mathematical model of precession in another aspect.
