Implementation aspects of radio spectrum monitoring and surveillance system in the VHF/UHF frequency band

The radio system for very/ultra high frequency (VHF/UHF) spectrum monitoring and signal processing used in direction finding is presented this paper. This main function based on the implementation of a 6-channel VHF/UHF receiver. multicoupler unit allows selection desired band analysis verified according to user requirements. Several measured electrical characteristics receiver are just illustrate their possibilities full application. Besides, menus both devices management briefly described.
