摘要
通过分析弹道目标的运动特性,给出了弹道、目标微运动、雷达观测三者相结合的仿真方法;根据仿真计算的飞行弹道背景中雷达观测的目标姿态角,结合弹道目标的静态数据,由此生成弹道导弹动态雷达回波序列.利用典型进动弹头目标的仿真结果,分析弹道类目标平动给微多普勒带来的影响,采用最小熵的平动补偿方法,去除径向加速度对微多普勒分析的影响.仿真结果说明该方法能够有效补偿平动影响.
By analyzing the motion characteristics of ballistic target, this paper proposes a simulation method that combines with such three factors as ballistic trajectory, target micro-motion, and radar observations, where, the radar＇ s dynamic echo sequence of ballistic missile is generated by the target attitude angle observed by radar in the background of flight trajectory computed by simulation, and by combining with the static data of ballistic target. By using the simulation results of typical processional motion warhead, the influences of translational motion of ballistic targets on micro-Doppler are analyzed, and the influences of radial acceleration on micro-Doppler analysis can be eliminated effectively by the translational compensation method with minimum entropy. Simula- tion results show that this proposed method can compensate effectively the effect of translational motion.
