摘　　要：针对传统锥形音频干扰技术在对CPM-LFM共享信号的干扰过程中不能有效干扰其目标识别功能的问题,提出一种改进的锥形音频干扰方法.该方法依据共享信号的部分幅值特征对锥形音频干扰信号的生成方式进行调整,提高了锥形脉冲串与共享信号的相关性,改善了其在目标识别过程中的干扰能力.最后进行了仿真,验证了其综合干扰效能.仿真结果表明,改进的锥形音频干扰方法能在一定功率条件下产生清晰的假目标干扰,目标检测的干扰能力得到提升.Aiming at the problem that traditional conical audio jamming technology is unable to effectively interfere with its target recognition function in the process of interference to the CPM-LFM shared signal,this paper presents an improved conical audio interference method,in which the generation mode of tapered audio interference signal is adjusted based on the partial amplitude feature of shared signal,so as to increase the correlation between the conical pulse string and the shared signal,and improve the ability of interference in target recognition.Finally simulation is done to verify its comprehensive interference efficiency.The simulation result shows that the improved conical audio interference method can produce clear pseudo target interference under certain power conditions,with the interference capability of target detection improved.
