FIELD: hydroacoustic ranging devices. SUBSTANCE: device has bottom bed reference network which has M hydroacoustic receivers which have different response frequency, hydroacoustic transmitter which request frequency is f, generator of synchronization pulses, M-channel receiver which has acoustic input for response signals, M gauges which measures time for double-way spreading of hydroacoustic signals to and from response unit, which operates at frequency of these channel, MxN transducers which convert time intervals into distances according to number of beam trajectories, and unit, which calculates coordinates of navigation object. All latter units are mounted on navigation object. In addition navigation object has six-element acoustic receiver with acoustic input for receiving of response signals, which elements are located as three pairs of submarine detectors which are relatively orthogonal and spaced by distance which is less than wave length. In addition device has second M-channel receiver, each channel of which has three pairs of amplifiers, M phase difference detectors, M calculation units which calculates distance and sliding angle, and unit for setting invariant speed. In addition device has M beam selection units. EFFECT: navigation support of submarines. 1 dwg |
