VHF, UHF, SHF stationary radioreconnaissance and direction finding system

VHF, UHF, SHF stationary reconnaissance and direction finding system is designed for detection, direction finding and position finding of VHF, UHF, SHF radio emitters, which use traditional signals (fixed frequencies), as well as signals of advanced digital communication systems. The system can function both in autonomous mode, and as a part of multiposition automated system of radio monitoring and direction finding.
