The OMEGA-3K is designed for high speed analysis of RF spectrum, detection and identification of RF radiation sources simultaneously in two synchronous reception channels in the 30MHz~12GHz frequency range. Each channel can collect data from up to four spaced-apart antennas.

There is also a separate independent channel for detection and analysis of signals in the 9 kHz~30 MHz frequency range.

The OMEGA-2K has only one 30 MHz~12 GHz reception channel and a separate independent channel for detection and analysis of signals in the 9 kHz~30 MHz frequency range.

Input of the 30MHz~12GHz receivers is made as a superheterodyne circuit with frequency conversion by 15 GHz up.

This, together with a 10-channel preselector, ensures noise reduction in side channels of intermediate and image frequencies by 90 dB.

Intermediate-frequency multichannel section is made using digital vector processor according to SDR concept.

Radio signal is digitized on the second intermediate frequency of 140 MHz and with sampling frequency of 80 MHz.

The OMEGA-3K and OMEGA-2K are used together with the OMEGA-AM, OMEGA-A6, OMEGA-A12, OMEGA-16 Controlled Generators during investigations and studies of compromising emanations, for detection of resonant reradiators (resonant cavity passive transmitters and other secondary reradiators), spot jamming of eavesdropping transmitters.

When using the abovementioned controlled generators together with the OMEGA-AK Directional Coupler of Reflected Wave, it is possible to examine data processing equipment, connected to coaxial cables, by active methods in the frequency range of 30~6000 MHz.

The system operates in three main modes:
  • Analysis and display of RF spectrum/spectrograms in a set range (ranges) and in selected reception channels with required resolution and scanning speed.
    During analysis process, automatic detection of signals, which exceed set level, is done.
  • Detailed analysis of spectrum in a set frequency band.
  • Demodulation and/or recording of target signals in a band of parallel analysis.

There is a possibility of displaying two spectral panoramas or spectrums at one display in synchronous operation of two channels.

When reception is made with two spaced-apart antennas, it is possible to classify signals as local and external.

At parallel asynchronous operation, analysis and display of spectral panoramas can be done in one channel, spectrum analysis and signal demodulation - in another. Besides it is possible to carry out simultaneous spectral analysis of the same or different frequencies.
