本文对日益受注目的暂态信号参量阵的诸特性,如传播特性、转换特性、方向特性进行了较系统的研究.提出考虑到非线性吸收时计算暂态信号参量阵的计算方法.对于原波的线性吸收(吸收限制)和非线性吸收(饱和限制)情况下的参量阵进行了理论计算与实验研究,取得了较满意的一致性. In this paper, the characteristics of transient signal parameter array, such as propagation characteristics, conversion characteristics and direction characteristics, which are attracting more and more attention are studied systematically, and the calculation method for calculating the parameter array of transient signals considering nonlinear absorption is proposed. The theoretical calculation and experimental study on the linear and linear absorption (absorption limit) and non-linear absorption (saturation limit) cases are carried out. The results show a satisfactory agreement.
