Joint transient and CW external-noise mitigation in heavy clutter

A new method for interference mitigation which efficiently combines continuous-wave (CW) external-noise mitigation with transient and impulsive-noise mitigation in high-frequency over-the-horizon (HF OTH) radars is proposed in this paper. The efficiency of the method is demonstrated on real data collected by the JORN and SECAR HF OTH radars.
