摘要
本文试从非线性声学理论着手,讨论了参量阵所具有的低频高指向以及宽频带等特性。根据航海中现存的两个问题,指出参量阵在这方面的应用前景。
In this paper, it is tried to express the principle of nonlinear acoustics. The properties of parametric array appearing especially in the low freguency, sharp beam pattern, broad bandwidth are theoretically and experimentally discussed. Then, the application features is predictad by applying it to two kinds of typical navigation problems for underwater inst ruments.
