For detection of target submerged in the spread Doppler spectrum of the first‐order sea clutter in shipborne high‐frequency surface‐wave radar (HFSWR), there still remains a challenge. In this study, an improved orthogonal weighting (OW) algorithm is proposed for shipborne HFSWR to suppress sea clutter in both Doppler domain and spatial domain. By combining OW with the method of sea clutter suppression in Doppler domain, the performance of azimuth estimation of OW is thus preserved. Compared with OW and two‐dimensional fast Fourier transform plus digital beamforming, this new approach is verified to be more effective by simulations and real data.
