1. A method of compressing data from a sonar system comprising the steps of:
providing an acoustic transceiver including a transmitter and a receiver, the acoustic transceiver interconnected with plural transducers in a single projector array and plural transducers in a single hydrophone array;
exciting the projector array with a transmitter message such that a particular geometric space is ensonified;
receiving echoes via the plural hydrophones from the geometric space at each of plural times t1, t2, . . . tz;
at each of one or more of the times tx, forming Q receive beams with respective angles of arrival, the Q receive beams formed by the hydrophone array;
associating each of the Q beams with a magnitude Mtx,i indexed by the time tx and beam number i; and,
identifying as characterizing beams one or more beams with largest and next largest magnitudes at each of the times tx;
wherein compressed data results from using data associated with the characterizing beams as a compressed characterization of the ensonified space.
