摘要

在对声压相梯度正交投影在“距离-频率”平面上的不变性进行稳定估计的基础上，提出了水声场不变性的新定义。这一定义将不变量的概念推广到所有现有的浅海和深海区域，包括深海照明的近区和远区，在这些区域不可能估计和应用Chuprov干涉不变量。在丘普罗夫不变量的存在区内，它的值与新不变量的值几乎一致。

A Generalized Approach to Interference Invariant of the Hydroacoustic Field in Deep and Shallow Seas

A new definition of the hydroacoustic field invariant based on a stable estimate of the invariance of orthogonal projections of the sound-pressure-phase gradients on the “distance–frequency” plane is introduced. Such a definition generalizes the concept of an invariant to all existing zones of shallow and deep seas including the near and far zones of illumination of the deep sea in which it is impossible to estimate and apply the Chuprov interference invariant. In the zone of existence of the Chuprov invariant, its values almost coincide with the values of the new invariant.
