Abstract

This invention relates to a movable dual channel radio monitor and related interference direction finding system including a movable vertical polarized related interferometer direction finding antenna array, high and low ends rotation switches, an antenna selector, a three-function RF amplifier, a dual channel monitor direction receiver, a monitor direction controller, an industrial control computer, a low end vertical polarized monitor antenna, a high end vertical polarized monitor antenna, a monitor/direction finding selector, a GPS, an electronic compass, an UPS, an environment moinitor and remote control supply unit and a concentrator, which is advantaged that the mutual couple and fuzzy phase among antenna arrays are overcome by applying large aperture active/passive movable direction finding antenna array, and a pair of antenna elements sample at the same time so as to secure synchronous, quick and accurate and the system has three functions of amplification, direct pass and attenuation.

Description

technical field [0001] The invention relates to a portable dual-channel radio monitoring and related interference direction finding system, which belongs to the technical field of array signal digital processing direction finding in communication technology. Background technique [0002] In reality, a fixed monitoring station has high direction finding accuracy, but it requires a certain scale of installation platforms (such as high-rise buildings, iron towers), and fixed station equipment (including antennas, cabinets, etc.) are relatively large and heavy; while mobile stations are more mobile Well, just slightly lower performance than fixed stations. Accordingly, a portable station with simple configuration and flexible mobility between the two has become a major demand. Contents of the invention [0003] The purpose of the present invention is to propose a portable dual-channel radio monitoring and related interferometric direction-finding system, which is equipped wit...
