摘要

提出了一种同步信标水下目标测距声速剖面(SSP)反演算法。在实际SSP不可用的情况下，在多径传播时延估计的基础上，采用遗传算法通过特征射线传播时延匹配估计目标距离和SSP。湖泊试验结果表明，该算法可以同时实现目标测距和SSP反演。

Underwater Target Ranging and Sound Speed Profile Inversion via Eigenray Propagation Time-Delay Matching

An underwater target ranging and sound speed profile (SSP) inversion algorithm for synchronous beacon is proposed. In the condition of actual SSP unavailable, based on the multipath propagation time-delay estimation, a genetic algorithm is employed to estimate the target range and SSP by eigenray propagation time-delay matching. Lake trial results show the algorithm could achieve target ranging and SSP inversion simultaneously.
