基于目标速度信息的海上编队目标选择技术

Sea Fleet Target Selection Method Based on Target Velocity Information

为了提高反舰导弹对舰艇编队中预定目标的选择能力,提出了利用舰艇编队相互位置关系和速度信息选择预定目标的方法。该方法提出首先利用Hausdorff距离将火控雷达和末制导雷达探测到的编队点集进行最佳位置匹配,然后利用双向最近邻准则计算获取点集的对应点,最后利用目标的速度信息,进一步剔选对应点。提出了利用目标速度信息与编队信息的复合距离度量方式,并分析了对预定目标选择的概率。仿真计算表明,该方法不受自控终点散布误差和编队目标整体机动的影响,且正确选择预定目标的概率高于只利用编队信息进行目标选择的方法。

To improve the selection capability of anti-ship missile over the intended target of the ship formation, a method is present to select intended target by utilizing the ship formation＇ s mutual position and velocity information. Firstly, this method takes advantage of the hausdorff distance to match the optimum position of the point set which was respectively acquired by the fire control radar and terminal guidance radar. Then, the point set corresponding points are acquired by the bidirectional nearest neighbor rule. At last, the corresponding points are get rid of by utilizing the velocity information of the target . The composite metric distance method is present by utilizing the target velocity information and the formation information, and the selection probability of the intended target is analyzed. The simulation experiments show that this method is free from the influence of the dispersion error of the control end and the whole maneuver of the formation target , and its correct selection probability of the intended target is higher than the method which uses the formation information only.
