一种基于卡尔曼滤波的动态相对位置解算算法

An Algorithm of Dynamic Relative Position Based on Calman Filtering

在舰船海上校飞过程中,测量解算飞机相对舰船的位置会产生一定的误差。采用直接算法在解算中没有对粗大误差和GPS信号缺失进行处理,解算结果误差较大。提出了一种改进的相对位置解算算法。通过仿真实验,从方位角、俯仰角和距离3个方面,对改进算法的解算精度和直接算法的解算精度进行分析比较,仿真结果表明,改进算法能很好的提高相对位置解算精度。

In the process of ship flying school, to compute the relative have a certain error. Direct algorithm of gross error and loss of GPS sig in the calculation results. A relative position improved algorithm is proposed position of aircraft and ships n aling processing make error Through the simulation experiInent, for the three aspects of the azimuth angle, pitching angle and distance, the precision of calculation accuracy and direct algorithm improved algorithm are analyzed and compared. The simulation results show that, the improved algorithm can improve the relative position accuracy very much.
