Multichannel receiving HF module
Main features:
1. Multifunctionality. The possibility of solving communication problems, the problems of direction finding and radiomonitoring.
2. Open architecture. The possibility of program reconfiguration:
changing information protocol, remote control protocol, etc.
changing signal processing modes, as well as signal processing algorithms.
3. Scalability
4. High sensitivity in connection with the dynamic characteristics.
As a part of the communication center it allows solving the problems of enhancing the reception quality under the influence of radiostation interference, at the expense of digital forming of patterns of phased arrays, enhancing the equipment reliability and providing the possibility of its step-by-step evolutionary modernization. While operating the complex, a frequency-reference signal forming device is included in order to control the phased array.
