SPACE-TIME ADAPTIVE PROCESSING FOR AIRBORNE RADAR -A CONVENIENT IMPLEMENTATION APPROACH
-
摘要: 本文提出了一種便于工程實際實現(xiàn)的機載雷達空時二維自適應(yīng)處理方法,其特點為在主雜波區(qū)增加輔助陣元。經(jīng)理論分析和計算機模擬表明,這種方法可以通過空時兩方面有效地抑制地雜波,獲得優(yōu)良的系統(tǒng)性能,同時運算量小,實現(xiàn)方便,具有工程應(yīng)用前景。同時本文還對在主雜波區(qū)增加輔助波束的方法進行了分析研究。

Abstract: A convenient implementation approach of space-time adaptive processing for airborne radar has been proposed, which is added by some auxiliary array elements in the area of main-lobe clutter. It is of practical use for its small computational load. Since this approach possesses the ideal performance in the area of main-lobe clutter so that it is adequate to the phased array radar which the array antenna is placed on the aircraft by non-facade side. In addition, the approach which is added by some auxiliary beams in the area of main-lobe clutter has been discussed. -
