The single satellite direction finding method and the direction finding method of the rotating interferometer are limited to the processing capability and precision of the traditional electronic reconnaissance satellite. A multiple objective twodimensional angle estimation method based on the rotating baseline is proposed. In this method, the multichannel rotated long baseline interferometer model is combined with the array signal processing method, and the two dimensional angle information of the target is extracted by the Hough transform according to the change rule of the angle ambiguity. On the basis of the proposed method, the relationship between the position of the angle ambiguity and the angle of the rotating interferometer is analyzed, and the time dimension distribution model of the grating valve is established. The simulation results show that the proposed method can effectively extract the accurate angle information from a plurality of angle ambiguity. Compared with the traditional rotation interferometer direction finding method, the proposed method can achieve multiple objective twodimensional angle estimation and reduce the requirement of signal to noise ratio.
