Analysis and Optimization Algorithm of Air Positioning Radio Frequency Interference

Air positioning radio frequency interference is an efficient and quick interference monitor method used to purify the aviation electromagnetic environment and ensure the safe operation of civil aviation. Firstly this paper introduces the air direction finding system based on Adock Watson-Watt methods, and analyzes the technology roadmap of positioning radio frequency interference in flight. On this basis, compared with the existed air positioning methods, it proposes to use the K-means algorithm to optimize the interference source positioning result to get rid of positioning errors caused by aircraft maneuvering and errors of direction finding antenna array.
