摘　　要：为了准确检测弹丸的入靶参数,提高精度靶检测性能,在分析弹丸定位算法的基础上,建立基于天幕靶与声靶的五元定位模型,进一步提出一种弹丸入靶参数检测算法。根据模型间各阵元的矢量关系,推导出弹丸入靶参数的计算公式,实现弹丸入靶参数检测。利用阵列参数,偏航角和弹丸入靶坐标点到阵元中心距离与定位性能关系,对测距测向精度进行分析。结果表明,该算法弹丸入靶坐标最大误差为1.41%,方位角最大误差为1.23%,具有较好的弹丸入靶参数检测效果。In order to accurately detect the target parameters of projectiles and improve the accuracy of projectile detection performance,based on the analysis of projectile detection algorithms,a five-element array model based on sky screen and acoustic targets is established,and a target parameter detection algorithm is proposed.According to the vector relationship between the elements,the calculation formula of the target parameter detection algorithm is derived to realize the detection and positioning of the projectile entering the target point.Using the array parameters,the yaw angle and the distance from the projectile’s target point to the center of the array element and the relationship between positioning performance,the accuracy of ranging and direction finding is analyzed.The results show that the projectile’s target point coordinate error of the algorithm is 1.41%,and the azimuth angle error is 1.23%,and it has a good detection effect of projectile entering target point parameters.
