Claim 16:
17. A multifan survey method comprising the steps of:
constructing a message with N>=3 message components for ensonifying reflectors in N elongated fans, each message component distinguished from other message components by a code;
processing each message component in a respective transmit beamformer;
driving each of plural projectors with signals derived from all of the beamformers;
transmitting N beams from the projectors, each beam ensonifying reflectors in a respective one of the elongated fans;
forming multiple receive beams with each of N receive beamformers, the beams intersecting the elongated fans;
receiving returns from the reflectors via the receive beams; and,
acquiring survey data at multiple ones of the intersections, the data at each such intersection associated with a particular fan via the message component code.
