Monitoring and direction finding system

The mobile radio monitoring and direction finding system is a mobile means of radio monitoring and direction finding,which can make up for the lack of coverage of fixed monitoring stations and the need for on-site monitoring and direction finding.The system is mainly designed to complete routine monitoring tasks and special monitoring tasks in key areas and special areas.The company can provide towed special monitoring vehicles that can flexibly replace dedicated radio frequency tube equipment for specific application scenarios,alongside comprehensive radio monitoring vehicles that support full-time operations.

MAIN FUNCTIONS

PARAMETER INDEX

The company provides category I II,and I mobile monitoring stations that meet China's latest “Provincial Radio Monitoring Facility Construction Specifications and Technical Requirements”.The largest monitoring direction finding frequency range covers 20MHZ-18GHz,and adopts a variety of direction finding systems such as relevant interferometers orfull-band spatial spectra,which can support direction finding forup to 5signals with the same frequency
