摘要: 自適應(yīng)抑制機(jī)載預(yù)警(AEW)雷達(dá)雜波的問題近年來受到了廣泛關(guān)注。有效進(jìn)行自適應(yīng)處理的必要條件是系統(tǒng)可控自由度數(shù)大于雜波自由度數(shù)。本文詳細(xì)研究了相控陣AEW雷達(dá)的雜波自由度問題,得到了一些新結(jié)果。這些結(jié)果有助于設(shè)計(jì)自適應(yīng)系統(tǒng)。Abstract: In recent years, adaptive clutter suppression for airborne early warning (AEW) radars have attracted considerable attention. A necessary condition for efficient clutter suppression is that the number of adaptive degree of freedom (DOF) is greater than the number of clutter DOF. This paper analyzes DOF of clutter for phased array AEW radars. The new results obtained are helpful to design a adaptive , system for clutter suppression.
