FIELD: electronics.
SUBSTANCE: receiving ship subsystem in short-wave range includes attenuators, phase changers, microcomputer and adders. Microcomputer is connected with coordinates and course sensors, as well as with an analogue-to-digital converter, which is connected to radio receivers. Signals from active antennae are separated by means of a broadband antenna into required number of channels from 8 to 64 through a switch of receiving antennae, and signals are transmitted to input of radio receivers from active antenna array or from single antennae.
EFFECT: technical result is providing electromagnetic compatibility of communication means in conditions of surface ships.
