Abstract

Abstract

If the azimuth angle between the interference and the detected target is small, the energy of the received signal reflected by the target may have a great loss when the interference is cancelled for an omni-directional VHF radar with single circular array. To resolve this problem, an improved algorithm based on double circular arrays is proposed. The algorithm firstly utilizes the excited phase mode -1, 0 and 1 of the small array to estimate a rough azimuth angle of the interference, and then acquires an accurate one by symmetrical phase modes of high orders of the large array. Finally, interference cancellation and estimation of targets azimuth angle are fulfilled via unsymmetrical phase modes of the large array. Compared with the algorithm based on single array, the proposed algorithm can reduce the energy loss of the useful signal and increase the estimation precision of targets azimuth angle. Simulation results demonstrate the effectiveness of the proposed algorithm.
