本文叙述了参差调谐宽带换能器频率布阵优化方案的计算机模拟。根据扫描系统分辨率的要求,指出频率布阵优化方案必须满足两个条件:1.阵列中任何有限区间的频率响应,都应满足一定的带宽。2.阵列的波束空间响应是最好的。为此必须首先把频率级数序列阵按有限区间响应重新整序排列;其次,使重新整序排列后的波束指向函数与一给定的较优指向函数等价。根据采样合成定理就可模拟出重新整序后的参差阵的布阵方案。 This paper describes the computer simulation of the frequency tuning optimization of the staggered tuned broadband transducer. According to the requirements of the resolution of the scanning system, it is pointed out that the frequency distribution optimization scheme must satisfy two conditions: 1. The frequency response of any limited interval in the array should meet a certain bandwidth. 2. Array beam space response is the best. To do this, we must first rearrange the array of the frequency series according to the finite interval response. Secondly, make the beam pointing function after the rearrangement order equivalent to a given optimal pointing function. According to the sampling and synthesis theorem, we can simulate the rearrangement of the matrix after the staggered array.
