Abstract :
Based on a dual-polarisation high-frequency surface wave radar system, main characteristics and performance of sky wave interference are described, and a new polarisation filter, adaptive phase-shift polarisation filtering, is applied. Suppressing the interference in each pulse and keeping the original phases of the targets, about 20 dB signal-to-interference ratio is expected with experimentally derived data.
