Abstract :
The co-channel radio frequency interference (RFI) is the most common interference encountered in high-frequency surface wave radar (HFSWR). Normally each RFI shows a line in the range-Doppler map, across all range bins at a certain Doppler frequency, which significantly affects the radar target detection performance. In this paper, the characteristics of co-channel RFI in range, Doppler and spatial domain are analyzed in detail. Then several adaptive beamforming based RFI cancellation techniques are evaluated and compared using experimental data, and the most preferable technique in practical HFSWR environments is recommended.
