摘要
本文介绍一种便携式高精度水下高速运动体三维轨迹测量系统。文中叙述了定位解算数学模型、主要误差源、水下基阵校准及姿态修正方法。对距离模糊、多途干扰等问题亦作了分析。最后给出了部分湖上及海上试验结果。
The paper describes a portable high precision three-dimensional trace measure system for high-speed underwater target. The mathematical model for location, the main error sources, the calibration method for underwater array and the way to correct the state of the underwater array are discussed. Some problems about the distance ambiguity and multi-path interference are also analysed. Some experiment results on the lake and the sea are given.
