FIELD: hydroacoustic equipment.
SUBSTANCE: invention relates to hydroacoustic equipment, in particular to on-board equipment of autonomous unmanned underwater vehicles of light and medium class modular design, intended for examining the bottom topography, sunken objects and artificial structures. The use of three receiving linear antenna arrays in MES, providing the possibility of forming three fans of static DCs, uniformly overlapping a wide viewing sector, in each of which the DC is tilted in a narrow sector with an insignificant expansion of the main lobe, made it possible to increase the detail and accuracy of the calculated depth profiles of the surveyed surface in the direction of the extreme DC of the receiving AS.
EFFECT: increasing the detail and accuracy of the calculated profiles of the depths of the surveyed surface in the direction of the extreme DC of the receiving AS.
