THE NATURE OF GROUND CLUTTER AFFECTING RADAR PERFORMANCE

The purpose of this paper is to study and evaluate some types of clutter which causes the degradation of radar performance. This study will take into account the clutter introduced from land, and other manmade objects such as large buildings and so on. Otherwise clutter targets reduce radar performance because of difficulty of separating them from moving targets and the detection of target in such a situation affects the operating capability of radars. Clutter targets are either isolated or composed. An isolated target is on which can be considered as a ''point'' scattered. It's sufficiently small in size to be included with in the area covered by the antenna beam. With the composed clutter target is more usual and it's characterized of most ground clutter. It consist of many individual scatters within the coverage of the radar antenna beam
