摘　　要：回波仿真是开展系统论证和算法研究的基础。传统的弹道目标雷达回波仿真研究侧重对弹道目标和干扰信号各自特性的建模,缺乏系统级联合仿真途径。文中介绍了一种基于场景定义的弹道目标动态雷达回波仿真方法。该方法基于统一的人工场景定义平台,结合弹道轨道运动模型、摆动模型和电磁干扰模型,模拟产生高逼真度的摆动弹道目标雷达回波。该方法还可灵活接入暗室或靶场实测的目标雷达散射截面数据和干扰样本数据,为复杂电磁环境下的导弹目标探测和识别算法研究提供数据支撑。Echo simulation is the foundation of system demonstration and algorithm research.The traditional echo simulation focuses on the methods of modeling the missile and the jamming signal independently,lacking system-level simulation.This paper presents a micro-motion ballistic object radar echo simulation method.Based on a manual scenario-definition platform,this method generates high-fidelity radar echo of ballistic objects,where ballistic trajectory model,wobbling model and the jamming model are integrated.This method can also be connected with target radar cross section data and jaming smapling data from dark room or real data,providing an important data platform for detection and recognition of warhead in complex electromagnetic environment.
