摘　　要：有源干扰机的行为参数测试是雷达抗干扰技术的前提和基础,具有重要的研究价值。针对数字射频存储器(DRFM)干扰机行为参数测试问题,文中设计了一种基于序贯波形的DRFM干扰机行为参数测试方案。该方案针对干扰机信道化、瞄频、转发、分选以及策略方式设计了行为参数集合,并根据行为参数对干扰机干扰能力进行了划分,同时提出了一种基于序贯波形的DRFM干扰机行为参数测试方法,该方法基于层次分析法(AHP)和逼近理想解的排序方法(TOPSIS)进行干扰能力识别。仿真结果表明,在干噪比为2 dB时,干扰机行为的识别正确率达到90%以上。Behavior parameter test of active jammer is the premise and foundation of radar anti-jamming technology,and has important research value.For the jammer behavioral level parameter testing problem of digital radio frequency memory(DRFM),a behavior parameter test scheme for DRFM jammer based on sequential waveform is proposed in this paper.The scheme realizes the analysis and estimation of jammer channelization,frequency targeting,forwarding,sorting and strategy mode capability,which provides a new idea for effectively countering DRFM jammer.At the same time,the jamming ability recognition algorithm based on analytic hierarchy process(AHP)and technique for order preference by similarity to ideal solution(TOPSIS)is proposed.The simulation results show that the recognition accuracy of this scheme is more than 90%when the interference to noise ratio is 2 dB.
