When flying in formation, the UAV cluster should maintain its own flight line. However, in order to avoid outside interference, electromagnetic silence needs to be maintained as much as possible, and few electromagnetic wave signals are emitted to the outside world. Therefore, pure azimuthal passive positioning is used to adjust the position of the UAVs. In this paper, according to some models and specific requirements of transmitting UAVs, the standard positioning of UAV flight, UAV number, the positioning model of passive receiving signal UAV is established, and then the final accurate positioning is achieved by limiting the relationship between the size of the top angle and the angle of the transmitter. In the case that only the location and number of two UAVs, FY01 and FY02, are known, it is determined that several more UAVs with unknown numbers are needed to accurately locate the UAVs receiving signals. On this basis, this paper designs an adjustment scheme to adjust nine aircraft to a certain circumference with uniform distribution, ideally with a radius of 100m and the point FY00 as the origin, but only one of the initial positions of the nine UAVs is located in this circumference. A local optimal solution is selected, and the optimal solution is continuously updated through iteration, and finally the value with variance less than 0.5 is regarded as the optimal solution.
