摘要: Abstract SEAPIX is a new multibeam echosounder (MBES) with an original architecture using steerable symmetric Mills Cross. This configuration allows to image water column and sea bottom in both athwartship fore-and-aft direction. Furthermore, steering capability transmit receive volume coverage of 120° × 120° under ship 1.6° × 1.6° beam aperture on the antenna axis. 64 beams are acquired per ping frequency range 145–155 kHz monochromatic or modulated burst. Transmitted stabilized roll pitch according transmitted mode receiving motion compensated embedded inertial unit. MBES has been designed be installed fishing vessel help strategies as long provide useable data for fish scientist. First part this paper describes hardware main characteristics SEAPIX. We then describe signal processing functionalities Finally, we illustrate first results typical case.
