This article focuses on the method of adjusting the position of unmanned aerial vehicles using bearings-only passive positioning. Based on the plane geometric relationship, a unmanned aerial vehicle positioning model, a circular queue adjustment scheme, and a conical queue adjustment scheme are established, and MATLAB is used to solve the known data.Firstly, the line connecting FY00 and FY01 is used as the polar axis of the polar coordinate system, and the sine theorem in the triangle is used to obtain the functional relationship between the polar diameter offset and polar angle offset with the angle received by the receiving drone. Based on this relationship, a positioning model for passive signal receiving drones can be established. The relative position relationship between the passive receiver and the two transmitters on the circumference, as well as the positive or negative offset, can lead to differences in the model. Expressions for the angle and offset in polar coordinates in four different situations can be obtained.
