三角形五元十字混合阵列弹丸落点定位方法

A Projectile Impact Point Location Method Based on Hybrid Array Composed of Triangles and Five-element Crosses

针对靶场弹丸回收试验中弹丸落点定位精度低的问题,提出基于三个五元十字阵列组成三角形混合阵列的定位方法。该方法通过将三个五元十字阵列的中心传感器放置成为三角形阵列,以此组成混合阵列对弹丸落点定位,解决了五元十字单基阵定位精度低、双基阵对于特殊范围落点定位误差大的问题。仿真试验结果表明,采用混合阵列对弹丸落点定位的精度误差在1%以内,满足靶场对弹丸落点的全域定位精度要求。

In order to solve the problem of low accuracy of projectile impact point location in projectile recovery test in shooting range,a triangular hybrid array based on three five-element cross arrays was proposed.In this method,the center sensors of three five-element cross arrays were placed into triangular arrays to form a hybrid array to locate the impact point of the projectile,which solved the problems of low positioning accuracy of five-element cross single array and large positioning error of double array for special range.Simulation results showed that the accuracy error of the hybrid array for locating the impact point of the projectile was less than 1%,which met the global positioning accuracy requirements for the impact point of the projectile in the shooting range.
