摘要
为解决兵器实验场实验中炸弹落点测量问题,根据被动声定位的原理设计了一套被动声传感阵列测向测距系统。讨论了被动声传感阵列测向测距系统设计中的器件选型、信号时延估计、定位计算、后处理等方面的技术问题,在此基础上根据具体的工作环境设计实现了一个被动声传感技术阵列测向测距系统并进行了实验。对实验结果的讨论表明,该系统可以有效满足要求。
For the purpose of locating projectile dropping point in weapon test field, a new system was designed based on the passive acoustic localization principle. This paper discusses the design details of the passive acoustic localization system of sensor array, such as parts selection, time delay estimation, locating calculation and post processing. A real system was implemented on the basis of the application environment, and its performance was tested and the experimental results were discussed. The experimental results show that, this system can meet the requirements.
