Sonar beam-forming with an array processor in real time

Thumbnail
Abstract
A real-time sonar beam-forming system is described which consists of a minicomputer as host computer and an array processor. Beam-forming is accomplished by using the FFT algorithm in the processor. The system is also connected to a multi-channel PCM magnetic tape recorder. Processing can be done either on-line or offline. During sea trials the entire equipment is installed on board a research vessel. An acoustic towed array supplies up to 40 input signals to the beam-former. The AP 120 B from Floating Point Systems is used as the array processor
