A instantaneous passive location method has been put for aerial vehicles in this paper. The corresponding mathematical model is built via the data analysis of the direction finding array. Using genetic algorithms to calculate instantaneous passive positioning parameters of aerial vehicles based on direction finding array. The calculation results show that: the application of the method can accurately calculate the position parameters of the aerial vehicles, and it can achieve passive accurate positioning of aircraft. The method is able to meet the accuracy requirements of the actual positioning and the accuracy error is smaller.
