| Abstract(in English) | ASLC(Adaptive Sidelobe Canceller) is an adaptive antenna that can form nulls in the incident directions of the interference signals. In the ASLC, when two interference signals impinge in near direction, norm of weight vector may become large. It causes amplification of receiver noise of auxiliary antennas and degradation of S/N. In this paper, when the ASLC with two auxiliary antennas are arranged on one side of phase center of main antenna, it is theoretically shown that the norm of weight vector becomes large. To overcome this problem, we propose the ASLC with auxiliary antennas arranged on both sides of phase center of main antenna. At last, it is demonstrated by the computer simulation that SINR(Signal to Interference plus Noise Ratio) improvement performance of the ASLC does not degrade although two interference signals impinge in near direction. |
