Description

technical field [0001] The invention relates to the technical field of radio direction finding, and more specifically relates to a multi-antenna single-channel optimized radio direction finding system and method. Background technique [0002] On the one hand, the development of society promotes the rapid development of the radio industry. As an important technical means for radio monitoring, technical investigation and electronic countermeasures, radio direction finding technology has attracted more and more attention from the industry. According to different direction finding principles, direction finding systems can be divided into amplitude method, phase method, Doppler method, time difference method and spatial spectrum estimation method, etc. [0003] The amplitude direction finding system is widely used in the field of radio direction finding because of its simple structure and stable performance. The amplitude method can be subdivided into the maximum signal method (...
