Abstract

The invention discloses a single antenna optimization amplitude comparison radio direction finding system and method, and relates to the technical field of radio direction finding. According to the invention, a fixed-unidirection directional antenna with known directional characteristics is used to receive a radio signal; the received radio signal is processed; and an optimization method is used for direction finding. The problem that direction finding sensitivity, accuracy and speed cannot be taken into account in the prior art is solved. The amplitude direction finding system and method have the advantages of high sensitivity and high accuracy, do not require high component consistency, and can quickly carry out direction finding. The invention further provides a direction finding system which can meet data required by optimization calculation. Optimization calculation is carried out on a measurement result. Real-time direction finding is quickly carried out. Stored data are used for post direction finding.

Description

technical field [0001] The invention relates to the technical field of radio direction finding, and more specifically relates to a radio direction finding system and method for single-antenna optimization ratio amplitude. 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...
