A novel nonstationary radio interference cancellation scheme was given to improve the performance of target detection in high frequency surface wave Over-the-Horizon radar. First, the optimum algorithm was proposed that suppresses the nonstationary interference to the utmost by modifying the array steering vector under the permitted error limit; then, a method based on the idea of maintaining the sea clutter response was introduced to settle the problem of floor increasing for the reason of the clutter scatter. The interference cancellation frame was synthesized by the two methods at last. And the experimental results show it is efficient to reject the nonstationary interference.
