FIELD: radar stations, in particular, for detection of surface-water and shore targets and finding their coordinates. SUBSTANCE: device has synchronization unit, transmitter, antenna, antenna switch, echo signal receiver, which has high-frequency amplifier, mixer, intermediate-frequency amplifier, unit of phase detectors, and unit of video amplifiers. Transmitter has frequency tuning unit, excitation unit, phase keying unit, power amplifier, generator of phase keys, pulse modulator, as well unit for secondary information processing and displaying, emission receiver, unit for detection and measuring, code-frequency converter, frequency shift unit and inter-period processing unit. EFFECT: increased emission security for constant or increased effective range. 12 dwgc
