Interference and Clutter Mitigation Based on SVD for HFGWR

  • 摘要: 該文針對(duì)高頻地波雷達(dá)探海工作期間高頻干擾嚴(yán)重海雜波強(qiáng)的特點(diǎn)，干擾抑制時(shí)引入海雜波約束條件，對(duì)自適應(yīng)陣列波束形成方法進(jìn)行了改進(jìn)，防止干擾抑制后回波中一階海雜波時(shí)域相關(guān)特性發(fā)生破壞而在頻譜上虛假展寬。然后，使用干擾抑制結(jié)果構(gòu)造時(shí)域采樣矩陣，由奇異值分解(SVD)方法獲得積累期間一階海雜波頻率的變化歷程，通過(guò)矩陣特征分析將一階海雜波濾除。最后，使用OSMAR2000實(shí)測(cè)數(shù)據(jù)檢驗(yàn)了本文算法的有效性。
    Abstract: HF ground wave radar encounters intense interference and clutter during operation in ocean environment. This paper presents an improved adaptive beamforming algorithm introducing clutter constraints which do not destroy the temporal coherence of first-order sea clutter and broaden frequency spectrum falsely after interference suppression. Furthermore, Singular Value Decomposition (SVD) for matrix constructed by interference suppressed data is employed to track frequency evolvement of first-order sea clutter during CIT and clear procedure by eigenvalue analysis is proposed. Experimental results demonstrate the effectiveness of presented algorithm using data acquired by OSMAR2000.
