摘要
弹着点定位是实弹射击中实现自动报靶的关键。利用弹头撞击钢质靶板产生的振动波到达四个顶点上的振动传感器的时间差，来实现弹着点的定位。弹着点的位置定位算法，利用两次加权的方法，消除噪声等因素产生的误差，最后经过实验测试，分别对一次、二次加权的结果进行仿真以及数据的拟合。结果证明，该算法对弹着点的位置估计随着加权次数的增加，也会更加接近实际值。
The location of impact point is the key to the realization of automatic target report in live firing. In this paper, we use time difference when vibration wave which is produced by bullet hits steel target plate reaches to four vertices vibration sensor to realize the location of impact point, and present the impact point algorithm, and then use the weighted method twice to eliminate errors that come from noise factors. In the end, the algorithm is tested, and the first and second weighted results are used to carry out simulation and data fitting. Results show that this algorithm on the position estimation of impact point will be more close to the actual value with the increased weighted number.
