  • 摘要: 受到實際條件的限制，自適應(yīng)旁瓣相消器通常不可能頻繁地更新自適應(yīng)權(quán)值，使得其在對抗空域非平穩(wěn)干擾時，會出現(xiàn)權(quán)值失配現(xiàn)象，嚴重影響干擾抑制性能。該文從空域密集干擾產(chǎn)生寬零陷的角度出發(fā)，提出一種適用于自適應(yīng)旁瓣相消器的零陷展寬算法。該算法通過對主通道的合成權(quán)值和輔助天線間的協(xié)方差矩陣同時進行錐削實現(xiàn)零陷展寬，錐削向量和錐削矩陣只與陣元位置和展寬寬度有關(guān)，可以離線計算，在線直接調(diào)用，實現(xiàn)簡單，適合工程實際使用。仿真實驗證明，該文方法可以有效展寬自適應(yīng)零陷，增強自適應(yīng)旁瓣相消器對抗空域非平穩(wěn)干擾時的穩(wěn)健性。
    Abstract: In practical application, the adaptive weight of the sidelobe canceller can not be updated frequently. Thus, the spatial nonstationary interference would lead to the mismatch between the weight and the snapshots, which seriously deteriorates the cancellation performance of the sidelobe canceller. A null broadening algorithm is proposed for the sidelobe canceller, which is performed by tapering the conventional beamformer output and the covariance matrix of the auxiliary elements simultaneously. The taper vector and matrix only depend on the elements location and null width meaning that they can be designed offline and are quite suitable for practical use. Simulation results verify the effectiveness of the proposed method.
