Abstract :
The performance of high-frequency wave over-the-horizon radar (OTHR) is affected by transient interference. Transient interference suppression results in the integrity of the target signal. Without suppressing on clutter before interference excision, a robust principal component analysis is applied to separate clutter and the target signal, and the target signal is recovered simultaneously. Experimental results show the effectiveness of the proposed method.
