Abstract

Abstract:

In order to solve the problem of DOA estimation for the array antenna under strong interference,the concept of preserving orthogonality and characteristic beam is defined. It is proved theoretically that the characteristic vector of the corresponding feature vector is guaranteed when the source power and the angle interval are both large. And a novel DOA estimation algorithm based on the interference source feature vector is proposed. Through the simulation and comparison of JJM algorithm it is shown that the proposed algorithm has a better statistical estimation performance than the JJM algorithm.

Key words: array antenna, electronic interference, direction of arrival, signal processing
