ABSTRACT:
Disclosed is a programmable data collection and relay circuit for a towed hydrophone array. The circuit is designed to prepare data concerning operation of the array to be interleaved with substantive data produced by the hydrophones to produce a single data stream for transmission to recording equipment. The circuit comprises (1) a plurality of sensor inputs, each of the sensor inputs adapted to be coupled to a sensor capable of sensing a physical characteristic within the towed hydrophone array, (2) a circuit for polling at least a portion of the plurality of sensor inputs to determine values of the inputs, (3) a circuit for storing programmed data concerning which of the plurality of inputs is to be polled and (4) a circuit for serially placing the input values in condition for insertion into a data stream transmitted along the towed hydrophone array.
