We describe a 4-channel radiometric system developed for registering pulses of submillimeter-wave radiation in the frequency band 210-530 GHz. The system employs a quasi-optical scheme with polarization demultiplexed channels, wherein subsequent frequency filtering and spectral signal detection are provided by quasi-optical bandpass filters and high-speed Schottky detectors respectively. The system has frequency resolution of the channels ~30-50 GHz and response time better than 2 ns and destined for registering emission of electromagnetic radiation in the vicinity of a double plasma frequency, which is produced at turbulent heating of dense plasma in the multimirror magnetic trap GOL-3 by a powerful relativistic electron beam of 10 microsecond duration.
