Research on bearings-only passive positioning based on unmanned aerial vehicle formation

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