摘要
对二元相控阵单指向性水听器的指向性影响因素进行了理论分析 ,并对部分影响因素进行了实验验证。结果表明 ,两个基元输出信号的幅值发生变化 ,或者其移相角度发生漂移 ,都会对单指向水听器的性能产生影响。这为单指向性水听器的设计制作提供了一定的参考依据。
Some factors influencing the direction of unidirectional hydrophone formed in array of two elements with electric phase shift were theoretically discussed, and some results were tested. The conclusions may be that the amplitude change of output signal of two array elements or the shift of phase angle of signal will have some influence on the performance of unidirectional hydrophone.
