基于被动声信号解算方法的高速目标轨迹测量

High-Speed Target Trajectory Based on Acoustic Signal Calculation Algorithm

摘要:

声学测量作为新一代外场测量系统的重要组成部分，为实现全天候、全地形下目标的有效轨迹测量起到重要作用。现有外场测量系统多依靠光、雷达等手段对目标进行定位追踪，轨迹测量，但光学轨迹测量精度极易受自然光线的影响，而雷达轨迹测量精度易被复杂电磁环境干扰，无法实现所有时段各类目标的轨迹测量。本文所提出的声学轨迹测量方法，对于超音速目标其测量精度优于10m，对于高亚音速目标测量精度优于10m。声学测量手段的出现弥补了外场观测手段的空缺，极大程度丰富了外场的观测维度。

Abstract:

As an important part of the new generation range measurement system, acoustic measurement plays an important role in realizing the targets’ trajectory under all-weather and all-terrain phenomenon. Existing shooting range measurement systems usually includes light and radar, which are interfered by the natural light and complex electromagnetic environments, respectively. Thus, the previous range measurement systems hard to achieve trajectory measurements in inclement weather. The acoustic trajectory measurement method proposed in this paper has a measurement accuracy of better than 10m for supersonic targets and better than 10m for high subsonic targets. The emergence of acoustic measurement has made up for the vacancy in the observation methods, and greatly enriched the observation latitude of the shooting range.
