岸基警戒雷达抗干扰性能评估方法

To deal with the jamming that the shore-based warning radar will face under the typical battlefield environment, a quantitative evaluation method of warning radar anti-jamming performance is proposed, which is based on theoretical analysis and field test. To cope with the noise jamming and dense-false-target jamming, the evaluation index system is proposed respectively. By using the expert statistical analysis method, the importance measures of the theoretical analysis part are determined, and the weights of each index in the part are calculated accordingly, and the weights of each evaluation index in the field test part are calculated by using the analytic hierarchy process (AHP) and the expert statistical analysis method. The anti-jamming performance is quantitatively evaluated by using AHP. Compared with the existing theoretical methods, this method refines the evaluation index system and it is more operable. Compared with the field test method, this method reduces about 15% of the field test items, it saves the field test time and reduces the complexity of the field test organization. The results of the evaluation example show that the quantitative evaluation results, which are calculated by the proposed method, are in accordance with the performance summary of field test of various radars.
