基于一维距离像识别的反导雷达配置模型研究

Deployment of Target Recognition Radar Based on Range Profile in Missile Defense System

为更好地发挥反导目标识别雷达的作战效能,针对目标识别雷达的实际配置问题,建立一种基于一维距离像识别的雷达配置模型。首先,根据目标识别雷达的反导作战任务,确定目标识别雷达的探测结束点,再利用雷达探测性能参数计算出目标识别雷达的可配置区域;其次,指出雷达视线与目标间夹角的稳定性是影响一维距离像识别的重要因素,并给出衡量其稳定性的指标,以覆盖率和雷达视线与目标夹角稳定性的最大化为目标建立雷达配置模型,给出求解方法;最后,通过实例仿真发现,在靠近弹道地面投影的区域雷达覆盖率较小,在弹道地面投影正向延长线附近区域,雷达视线与目标间夹角能保持较高的稳定性,有利于目标识别。以上结论可为反导体系建设中武器系统的实际配置提供参考。

To make full advantage of target recognition radar （ TRR） in missile defense and solve the practical problem how to deploy TRR,we established a model for TRR deployment based on range profile recognition.First,according to the mission of TRR in missile defense,the point where TRR can stop detecting was determined,and the area where TRR could be deployed was calculated out by using the performance parameters of the radar.It was pointed out that the angle between line of radar and target （ABRT） was the main factor that had effect on target recognition,and an index was given to weigh its stability.Then,a radar deployment model was established aimed at maximizing the coverage ratio and stability of ABRT.The method to solve this model was also given .Finally,simulation analysis showed that：1） When the radar is deployed in the area near trajectory projection,the coverage ratio is small;and 2） When the radar is deployed in the area near line of extended trajectory projection,the ABRT is relatively stable.The conclusions are useful for target recognition .
