| Abstract: | The over-the-horizon radar (OTHR) clutters affect the excision performance of sidelobe interference using adaptive beamformation. The sidelobe cancellation can decrease the effect of the clutters when the pulse compression is made in clear area, and reduced-rank sidelobe cancellation requires low computation. The performance of the method presented was analyzed. The simulation results show that the method can achieves good performance of interference excision despite its low computation complexity. |
