ABSTRACT:
A multibeam acoustic apparatus utilizing a linear array of hydrophone elements in a sonar system includes a cascaded ladder capacitance-inductance network for coupling electrical signals to and from the individual hydrophone elements. The hydrophone elements are connected in series and the natural capacitance of these elements provides the capacitive characteristics of the network. Shunt inductors supply the inductance characteristics and provide a phase characteristic inversely related to frequency. Variable cumulative phase delays are provided for signals applied to successive hydrophone elements whereby a sonar beam is formed in a direction determined by the frequency of the exciting signal.
