摘要
针对由于警戒雷达缺少俯仰角测量信息,不能进行精确的坐标变换,导致对跟踪雷达的引导效率较低的问题,文中首先利用先验知识建立了警戒雷达指示信息的概率描述模型;然后,结合蒙特卡洛采样方法完成了指示信息从警戒雷达坐标系到跟踪雷达坐标系的变换;最后,通过计算目标在跟踪雷达波位上的出现概率,确定了跟踪雷达搜索空域大小和波位编排顺序。仿真实验验证了文中方法的有效性。
Because of the absence of pitch angle in two-dimensional early warning radar, coordinate transformation can＇t be processed exactly, resulting in poor efficiency of cueing tracking radar. To deal with the problem, firstly, probabilistic model is established for the prior information. And then coordinate transformation is achieved by using Monte-Carlo sampling theory. Finally, the optimal search schedule of tracking radar is presented. The effectiveness of this method is testified by simulation results.
