Abstract

Due to decoy, the time sequence of the signals received by anti-radiation weapon antennas is inconsistent, the target radar can not be accurately shadowed through sampling the cutting-edge and trailing edge and the middle of the pulse when the classical multiple signal classification(MUSIC) and rotational invariance techniques (ESPRIT) are used. Two algorithms for estimating direction of arrival (DOA) of time inconsistency signal were proposed. The first algorithm based on ESPRIT algorithm can be used for independent signals, the second one based on MUSIC algorithm can be used for coherent signals. Computer simulation confirms that, compared with similar algorithms, the two new methods can get better performance.
