Pure azimuth passive positioning in attempted UAV formation flight

In order to maintain the formation of UAVs during flight, pure azimuthal passive positioning is generally used adjust position UAVs. accurately perform UAV positioning, this paper establishes a single-objective optimization model with passively received signals based on polar coordinates UAVs, combined geometric knowledge such as sine theorem and triangle properties. And then optimized improved, i.e., when information two known, how many additional are needed localization. Therefore, it was found that unknown numbers were determine by establishing new set equations achieve slightly deviated positions. The important effective solution.
