Abstract

The invention discloses an earth station electromagnetic environment interference measuring device, and relates to the technical field of radio communication. The device comprises a supporting device,an azimuth rotating platform, a standard gain receiving antenna, a polarization adjusting device, a dual-channel gating switch, a low-noise amplifier, a multi-channel matrix gating switch and a turntable controller. The device has the characteristics of simple structure, small size, light weight, convenience in operation and low processing cost, can realize measurement of multi-band interferencesignals, obtains the nature of an interference source and the infinite radiation compatibility of a selected station address and various interference sources, and finally determines whether the earthstation address meets the station building requirement or not. The device is especially suitable for early-stage electromagnetic environment interference source measurement during earth station antenna station building, and can provide important reference basis for earth station design, building and construction.

Description

technical field [0001] The invention relates to the technical field of radio communication, in particular to an earth station electromagnetic environment interference measuring device. Background technique [0002] With the development of modern science and technology, especially the rapid development of radio communication and information technology, the electromagnetic environment in space is deteriorating day by day, and sources of electromagnetic radiation interference are ubiquitous. At the same time, with the development of satellite communication technology, a large number of earth station antennas need to be built, and whether there are interference sources around the site will directly affect the signal quality of the earth station system and the cost of station construction. Therefore, through the electromagnetic environment interference test, it is very important to determine the pre-selected site and antenna installation location to obtain the possible interferen...
