摘　　要：弹头微动特征是雷达进行识别的关键手段之一。针对雷达基于微动特征目标识别方法的发展现状,提出了模拟RCS微动特征的干扰方法。首先,描述了BM弹头的微动特征产生的原理,给出了弹头雷达散射截面(RCS)的模型。其次,结合微动特征和RCS模型,模拟具有微动特征的中段弹头动态RCS。最后,利用动态特征RCS模拟雷达回波信号,对雷达进行干扰。仿真实验表明,模拟RCS微动特征的干扰方法具有可行性和有效性。The warheads micro-motion character is one of the key methods to radar recognition.Aiming at the development of radar target recognition based on micro-motion character,ajamming method based on the simulation of RCS micro-motion character is proposed.Firstly,the generation principle of ballistic missiles' micro-motion character is described,and the RCS model of warhead is given.Secondly,the RCS of the warhead with micro-motion character is simulated.Finally,the jamming is implemented by the RCS with micromotion character.Simulation results show the feasibility and effectiveness of the jamming based on the RCS with micro-motion character.
