High-frequency sky wave over-the-horizon radar (OTHR) suffers performance degradation from transient interference. The segmental subspace projection approach is applied to suppress the clutter and locate the transient interference. After interference excision by adaptive thresholding, the integrated Doppler spectrum is reconstructed based on compressed sensing. Experimental results have demonstrated the effectiveness of the proposed method.
