一种四元非典型阵水下超短基线声定位方法

An Approach to the Ultra-short Baseline Acoustic Localization Using Non-typical Array

针对水下目标探测与定位的实际需求,从超短基线阵被动声定位的基本理论出发,提出了一种可行的四元非典型阵定位模型。采用广义互相关时延估计算法,设计完成了一套基于DSP的被动声定位硬件系统,验证了算法的正确性。该硬件系统的定位误差小于1°。

Based on the passive localization theory of ultra-short baseline for acoustic detection and localization, a practical non-typical array with four elements was proposed. Adopting the generalized cross-correlation time delay estimation algorithm,a hardware system for passive localization based on DSP was developed test indicate the validity of the algorithm. The locating error of the hardware system is 1° less.
