摘要
提出一种对测量值中野值的修正方法,并通过卡尔曼滤波算法应用于航海雷达航迹外推中。通过对于卡尔曼滤波算法的Matlab仿真可以看出,未经过此种修正的外推航迹受到野值干扰相当严重,而经过此种方法修正以后,航迹外推的准确性大大加强,因此这种方法达到了减轻野值对航迹外推的影响,对保障船舶的航行安全起到了重要作用。
A method of wrong measurements＇ amendment is proposed, and through Kalman filtering calculation, applying it into navigation radar track calculation. By the Kalman filtering calculation＇s Matlab simulation,getting that not he amended wrong measurements makes the calculation results interfered seriously, and amended wrong measurements through this way makes the calculation results exactly. This method abates the wrong measurements＇ effect to track calculation,and guarantee the salty of vessel.
