摘要
浅海环境受季节、气候、地形等条件影响,声场具有显著的空时变化性,但由于空时采样不充分,通常不能确知环境参数。在环境参数失配的情况下匹配场处理(MFP)对目标的定位性能严重恶化。本文仿真分析了典型浅海环境中水深、声速剖面等参数失配对声源的距离和深度估计误差的影响,并从简正波模型的角度提出了解释。
Being affected by season, climate and bottom shape, sound field of shallow water significantly vary with space and time. The environment parameters are always uncertain due to insufficient space-time sampling. The performance of Matched-Field Processing degraded dramatically when there exists environment parameters mismatch. In this paper, effect of environment parameters mismatch to matched-field processing in typical shallow water is anglicized, and explanations are given from normal-mode theory standpoint.
