Simulation and simulation analysis of ship target radar echo

传统舰船目标雷达回波系统能够实现目标雷达回波的发送与接收,但回波频率多次折射发生回波衍射导致接收信号紊乱,为此设计舰船目标雷达回波实时模拟系统。优化雷达信号实时模拟器系统,完成多模块点对点接收;描述雷达串行多波束发射信号,实现雷达回波精准定位;针对运动扩展目标进行雷达回波频谱调制,通过目标特性分析,实现目标雷达回波实时模拟系统设计。实验数据表明,设计的雷达回波实时模拟系统比传统回波模拟系统的回波接受率高25%,说明设计的回波实时模拟系统具备极高的有效性。

Traditional ship target radar echo simulation system can realize real-time radar echo of the sending and receiving,but the frequency of the echo multiple refraction wave diffraction,received signal disorders,ship target radar echo real-time simulation system is designed for this purpose.Optimize the radar signal real-time simulator system,complete multi-module point-to-point reception; It describes the radar serial multi-beam transmitting signal and realizes the precise positioning of radar echo.The radar echo frequency spectrum is modulated by the moving target,and the target characteristics are analyzed to realize the real-time simulation system design of the target radar echo.The experimental data show that the designed radar echo real-time simulation system is 25% higher than the echo acceptance rate of the traditional echo simulation system,which shows that the designed echo real-time simulation system is highly effective.
