Abstract

The related vertical-polarized single-channel digital radio monitor and interferometer direction- finding fixed station system comprises: a direction-finding antenna for big fundamental interferometer, two electric switch units, an antenna selector, a RF pre-processor, a three- functional RF amplifiers, a single-channel receiver, a monitor controller, a industrial control computer, a high / low vertical polarized monitor antenna, a hub, a monitor and remote control unit for environment, and a UPS. This invention overcomes coupling among antennas, fit to process RF signal, enlarges dynamic application range for received signal, and has high feature-price rate.

Description

technical field [0001] The invention relates to a vertically polarized single-channel radio monitoring and related interference direction finding fixed station system, and belongs to the technical field of array signal digital processing direction finding in communication technology. Background technique [0002] With the continuous advancement of science and technology, the popularization of high-performance computers and the use of advanced signal processing methods make single-channel correlation interference direction finding possible. Combined with high-performance single-channel receivers, radio monitoring and direction finding can be realized. At present, similar products include the DDF190 single-channel system of German R / S company, but its price is quite expensive, and the direction finding speed is slow (the minimum signal dwell time is 50ms), which cannot meet the domestic demand. Contents of the invention [0003] The object of the present invention is to prop...
