本发明为声纳系统中使用水听器线列阵的多波束声设备,包含一个级联的电容-电感T型网络,用于各水听器与声纳系统的信号耦合。水听器为串联连接,这些基元的固有电容具有容性特性。并联电感提供感性特性,且产生与频率成反比的相位特性。对加到或来自水听器上的信号提供可变的累加相位延迟。由此,在激励信号频率所确定的某一方向上形成一个声纳波束。
The present invention is a multi-beam acoustic apparatus using a hydrophone array in a sonar system, comprising a cascaded capacitive-inductive T-network for signal coupling of each hydrophone to a sonar system. Hydrophones are connected in series, and the inherent capacitances of these elements have capacitive properties. Paralleled inductors provide inductive behavior and produce phase characteristics that are inversely proportional to frequency. Provides variable cumulative phase delay for signals applied to or from hydrophone. Thus, a sonar beam is formed in a certain direction determined by the frequency of the excitation signal.
