摘要:

针对常规兵器试验测试领域全天时地面炸点测试问题,设计并开发了一种由对讲机、数据采集卡构建的声学炸点测试系统;系统采用遥控装置解决测量分站对讲机的发射控制问题,中心站以多对讲机作为信号接收装置,采用同步数据采集卡实时采集回传的声信号;提出并实现了一种基于爆炸能量边沿识别的时延估计技术,用于后期数据处理和炸点坐标计算;试验结果表明该系统可以实现兵器试验爆炸点的声学定位,系统开发周期短、可靠性高、适应性强,具有一定实用性和推广价值。

Abstract:

An acoustic burst point test system is designed and developed by the radio and data acquisition card, for solving the problem of ground burst point test in the field of conventional weapon test. System use a remote control device to solve the radio emission control problem. Central station, by radios as signal receiving device, collects the real-time returned sound signal synchronously. A time delay estimation technique based on edge recognition of explosive energy is proposed, which is used for data processing and the calculation of the blast point coordinate. The experimental results show that the system can realize the acoustic location of burst point. The system with short development cycle, high reliability and adaption, has a certain practicality and popularization value.
