FIELD: instrument engineering. ^ SUBSTANCE: invention refers to hydroacoustics and can be applied in manufacturing of hydroacoustic antennas. An antenna module with digital output embodies an integral module combining functions of hydroacoustic signal reception and signal preprocessing: analogue signal multiplication, filtration and analogue signal to digital code conversion. There is disclosed integrated structure easy-to-make, adjustable, transportable and serviceable. The integrated structure is presented by two versions of design arrangement of the antenna module: number of channels more than 20 and number of channels less than 20. There is covered side benefit of the antenna module if bears function of output data compression. In this case, total number of multicore cables from the antenna modules to the main body is decreased that improves body strength and survivability of a vessel that carries the antenna modules. ^ EFFECT: such integral design allows improving electromagnetic noise immunity of the antenna module owing to the absence of interface cables to transfer analogue signals from the hydroacoustic receivers of the antenna. ^ 3 cl, 2 dwg |
