摘要
针对迫击炮的侦察定位问题,介绍了一种基于α-β-γ滤波的定位方法。该方法首先根据外弹道学确定弹丸飞行的质心运动方程,然后利用常增益的α-β-γ滤波跟踪求解弹丸的运动参数,最后通过龙格-库塔(Runge-Kutta)方法求解质心运动方程,并外推求得炮位位置。仿真结果表明,该方法在保证较高迫击炮定位精度的同时实时性能较传统方法大幅提升,有显著的工程意义。
For the locating problem of trench mortar, a locating method based on α-β-γfilter is presented. First, centroid moving equations are determined according to the exterior ballistics. Then the motion param- eters are solved by the α-β-γtracking filter with constant gain. Finally, the trench mortar position is de- duced by solving the eentroid moving equations with the Runge-Kutta method. The simulation results show that the proposed method has good locating precision with much shorter time compared with conventional method, and it is valuable for engineering.
