In order to counter the non-stationary short wave radio interference and improve the performance of target detection

a robust least squares interference cancellation algorithm based on the dual-polar receiver was proposed for high frequency surface wave radar.Based on the idea of convex optimization

we modify the sample of horizontal auxiliary channel

and get the best performance of interference rejection in the worst case error circumstance under the limit of maximum error bound.Converting the convex optimization question to simple one dimension search

we get the effective method to settle the optimal weight coefficient.The experimental result shows that the proposed method is very effective.
