【Abstract】 A new robust interference rejection method was proposed to confront the non-stationary radio frequency(RF) interference in high frequency surface wave radar(HFSWR) circumstance.By searching the optimal steer vector in the appointed error bound to get the best performance of interference rejection,a new robust Capon beamforming was used to reject the non-stationary interference in HFSWR circumstance,and the Newton’ method was used to settle the problem to get the optimal weight.The good performance of the new method was confirmed by the experimental data of experimental high frequency surface wave radar.更多还原
