It uses linearreceive and transmit arrays at a nominal frequency of 440 kHz to measure sea floor depth between 3-3000 m and a swath coverage of greater than 4x the water depth. It features a T-shaped array geometry. It also features a pitch-stabilised transmitter and an active roll compensated receiver. It has 512 high density equi-distant beams, an along-track beamwdith of 1.5 degrees and an across-track beamwidth of 2.0 degrees." . "accepted" .
