摘　　要：针对常规武器试验靶场火炮弹丸的终点坐标测量问题,提出一种多弹丸目标测量方法,研究其落地爆炸声信号传播特性,通过分析声信号传播衰减得到传声器的探测距离。依据与传声器探测距离匹配性制定部署方案,根据总体时间差误差最小的原则,制定多目标融合定位策略,对融合定位计算步骤进行了详细叙述。最后,通过外场试验验证了定位方法的有效性。Aiming at the problem of terminal coordinate measurement of artillery projectile in the test range of conventional weapons,a multi projectile target measurement method is proposed.The propagation characteristics of acoustic signal of landing explosion are analyzed.The detection distance of microphone is obtained by analyzing the propagation attenuation of acoustic signal.According to the matching with the microphone detection distance,the deployment scheme is formulated.According to the principle of minimizing the overall time difference error,the multi-target fusion positioning strategy is formulated,and the calculation steps of fusion positioning are described in detail.Finally,the effectiveness of the positioning method is verified by field test.
