Abstract
The external interference often reduces the performance of high-frequency surface-wave radar. In this paper, a novel interference suppression subsystem for HF radar is proposed, in which virtual auxiliary channels are constructed by a group of mismatched filtered signal data so that radio interference in the main beam can be effectively suppressed by a subsequent a coherent side-lobe canceller. The processing results of experimental data show that this subsystem is quite effective and practical.
