An Improved Direction Finding Algorithm Combining Correlation Interferometer and Generalized ESPRIT Algorithm

In this paper, an algorithm based on the combination of correlation interferometer and ESPRIT algorithm is proposed, which first uses the phase interferometer for the initial orientation and uses its result as the guide angle of ESPRIT orientation algorithm, which can effectively reduce the amount of operations of the generalized ESPRIT algorithm. The algorithm satisfies the realtime requirement and improves the anti-interference ability of the algorithm at the same time, and the simulation results verify the effectiveness of the algorithm.
