摘要
针对岸基警戒雷达在典型战场环境下将面临的干扰,基于理论分析与外场测试,提出了一种定量评估警戒雷达抗干扰性能的方法。针对噪声干扰与密集假目标干扰,分别构建了评估指标体系。运用专家统计分析法确定理论分析部分各指标的重要性度量值,并据此计算指标权重,将专家统计分析法与层次分析法(analytic hierarchy process,AHP)相结合,求取外场测试部分各指标的权重。运用AHP定量评估警戒雷达的抗干扰性能。与现有理论方法相比,该方法细化了评估指标体系,可操作性更强;与外场试验方法相比,减少了外场试验测试项目约15%,节省了外场试验时间,降低了外场试验组织的复杂度。评估实例结果表明,该方法计算出的定量评估结果符合各部雷达外场测试的性能总结。
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 about15%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.
