摘　　要：针对现有声学测量装置无法测量弹丸沿任意角度入射时的速度和空间位置坐标,且存在着较大误差的问题,提出了一种采用天幕靶配合声探测器测量弹丸位置参数的测试方法。通过分析声探测器所接收到激波时间,结合弹丸的过靶时间以及各个探测器空间位置信息,构建弹丸入靶参数解算模型。应用建立模型仿真分析,声光复合探测的着弹点误差率x方向低于2%,z方向低于1%。实验结果表明,对斜入射的任意速度的弹丸,基于声光复合探测的弹丸位置检测模型具有较高的精度。The existing acoustic measurement devices cannot measure the velocity and space position coordinate of projectile when it is incident at any angle, and there are large errors. A measurement method of projectile position parameters by using sky-screen target and acoustic detector are presented in this paper.By analyzing the shock wave time received by acoustic detector, combined with the passing time of projectile and the spatial position information of each detector, the projectile entering target parameter solution model is established. Based on the simulation analysis of the model, the error rate of the impact point of the sound-light composite detection is less than 2% in the x direction and less than 1% in the z direction. The experiment shows that the detection model of projectile position based on acoustic and optical composite detection has high accuracy for oblique incident projectile with arbitrary velocity.
