声测被动定位是弹丸落点定位技术的重要研究内容。传统的单基阵定位定距性能较差,而采用双基阵定位则可以有效解决这一缺陷。研究了双五元十字阵的平面交叉定位算法,对其定向和定距精度进行了理论推导和仿真分析,并进行了模拟实验。试验结果表明,双基阵定位相对定距和定向误差均小于2.5%,部分结果达到了理论分析的水平,性能较单基阵有了很大提升。

Passive location is an important aspect of impact point locating technology. The double-array location can resolve the weak ranging performance of the traditional single array efficiently. The cross algorithm of double-five-element-square-array structure was investigated, of which range and direction estimating precision analysis was conducted. The experiment shows that the relative range and azimuth estimating error of double-array locating method is less than 2.5%, part of the locating result has reached the level of theoretical analysis, and the range estimating precision is much improved than that of single array.
