摘　　要：针对对空情报雷达的有源欺骗干扰与目标回波高度相似,导致识别有源欺骗干扰难度较大的现状,提出了一种基于干扰机功率放大器非线性特性的有源欺骗干扰识别方法。提取分段自相关最大值方差和奇异谱熵两个特征,用这两个特征联合识别有源欺骗干扰。仿真结果表明,在信噪比大于等于8dB时,欺骗干扰识别概率能达到100%,能够满足实际工程需要。The high similarity between active deceptive jamming and echo of air surveillance radar results in the difficulty in identificating the active deception jamming. Based on jammerrs power amplifier nonlinear characters, a new active deceptive jamming identification method is proposed by extracting piecewise autocorrelation maximum variance and singular value spectral entropy of radar receiving signal. Simula- tion shows that the recognition probability for deceptive jamming is 100% with signal-to-noise ratio of 8 dB, meeting the actual engineering needs.
