Multi-beam swath bathymeter is a seafloor mapping equipment with high efficiency, high accuracy and excellent resolution, especially fitted for wide sweep mapping. The multi-beam swath bathymetric technique needs more improvement with the developing of modern science and technology. Miniaturization of the bathymeter is currently the main goal of this field.In this paper, the miniaturization of multi-beam swath bathymeter based on the H/HCS-017, the first multi-beam swath bathymeter of our country, was argue...
