Research on Interference Test of 24GHz Millimeter Wave Radar to 5G Equipment

Abstract

The millimeter wave frequency band tends to be developed with the application of radar and communication systems for civil use. It is necessary to analyze the interference coexistence between millimeter wave communication system and radar system. In order to make good use of frequency planning for the millimeter wave frequency band, a microwave anechoic room experiment is tested in this paper. The experiment includes a 24GHz 5G base station, a 24GHz 5G test terminal and a radar to verify the interference of 24GHz millimeter-wave radar to 5G equipment operating at nearby frequencies. This experiment tests and evaluates the detection capability of a single target in the limit state as much as possible and data of base station sensitivity, 5G uplink throughput and 5G downlink throughput have been tested in multiple situations to verify the accuracy and feasibility to this design of radar system. Therefore, the reference and support for 24GHz spectrum allocation can be provided through this method.
