摘要
针对水面舰艇鱼雷防御系统中双基阵纯方位定位问题,提出了修正极坐标卡尔曼滤波算法,分析了方位数据测量误差和时空关联对跟踪性能的影响。仿真结果表明,修正极坐标滤波可以快速、稳定地完成目标运动要素的估计,且该算法的稳定性有所增强,适合于工程应用。
Addressing the bearing-only positioning of two arrays in a surface ship torpedo defense,we present an algorithm of modified polar coordinates Kalman filter,and analyze the influences of measuring error of bearing data and time-space interrelation on tracking performance.Simulation results show that the modified polar coordinates Kalman filter can quickly and steadily estimate the target motion elements,and enhance the stability of the algorithm.The proposed algorithm is suitable for engineering application.
