Abstract

Intense RF (radio frequency) interference is the one of the impediments in target detection for high frequency surface wave radar (HFSWR). A novel type of HFSWR, bistatic HF surface wave SIAR (synthesis impulse and aperture radar), has been presented recently. In this paper, the RF interference of this radar is analyzed. Combining with the theoretical analyses and experimental samples, the features of the interference in temporal and spatial domain are investigated; and then an orthogonal projection based method in time domain is presented for mitigating the RF interference. The experimental result proves the validity of the proposed method.
