摘要
在雷达日常操作训练中,模拟训练系统可以较好解决实装设备使用受限的问题。雷达回波A显数据模拟可以降低模拟训练系统成本并提高系统灵活性。本文提出一种模拟算法从A显呈现效果的逼真性、实时性与互操作性出发,将A显信息按距离分为五部分,分别结合雷达波束、海杂波统计数据、目标回波和系统增益等模型,根据信号幅度特征对雷达回波进行模拟。此外模拟算法可实时响应雷达操作指令,根据雷达不同工作状态实时更新A显数据。实验结果接近真实回波效果,满足一定的操作训练要求。
In the daily operation training of radar, the simulation training system can better solve the problem of limited use of real equipment. The A-scope display data of radar echo simulation can reduce the cost of simulation training system and improve the flexibility of the system. In this paper, a simulation algorithm is proposed, which is based on the fidelity, real-time and interoperability of A-scope display. The information of A-scope display is divided into five parts according to the distance. The radar echo is simulated according to the characteristics of signal amplitude by combining the radar beam, sea clutter statistical data, target echo and system gain models. In addition, the simulation algorithm can respond to the radar operation instructions in real time and update the A-scope display data according to the different working conditions of the radar. The experimental results are close to the real echo effect and meet certain operational training requirements.
