Abstract
When airborne radar works on former mode, short-range clutter presents eyebrow shape curve and has the strong non-uniform, and clutter suppression is more difficult. Thus, the adaptive clutter suppression of forward-looking airborne radar for non-uniform clutter is a difficult question. Firstly, the use of a grid map method is taken for airborne radar forward-looking clutter model simulation analysis. Secondly, the forward-looking clutter suppression approach of airborne radar based on Knowledge-Aided Joint-Domain Localized (KA-JDL) algorithm of object filtering is proposed in this paper. Lastly, this new clutter suppression method is verified by the measured data. The experimental result shows that this method can suppress effectively the clutter compared with traditional JDL. It achieved a performance improvement of2-3dB.
