摘　　要：本文构建了一个集成的通信和感知系统,该系统具有感知目标并与用户通信的能力,并针对雷达探测性能和通信性能的平衡进行了优化。在海战场通信环境中,信号在传输过程中经常受到窄带干扰的影响,对通信质量造成很大损害。针对这一问题,本文设计了一套结合综合通信感知系统的窄带干扰抑制算法。该算法对经典阈值算法进行改进,实现阈值自适应。最后通过仿真说明了窄带干扰的危害以及去除窄带干扰的必要性,将窄带干扰下信号的误码率与本算法处理的信号进行比较,证明算法的有效性,将该算法与传统算法进行对比,证明了算法性能的提高。This article constructs an integrated communication and perception system with the ability to perceive target wells and communicate with users,and optimizes the balance between radar detection performance and communication performance.In the communication environment of naval battlefields,signals are often affected by narrowband interference during transmission,causing significant damage to communication quality.In response to this issue,this article designs a narrowband interference suppression algorithm that combines with a comprehensive communication perception system.This algorithm improves the classic threshold algorithm to achieve threshold adaptation.Finally,the harm of narrowband interference and the necessity of removing narrowband interference were demonstrated through simulation.The bit error rate of the signal under narrowband interference was compared with the signal processed by this algorithm to prove the effectiveness of the algorithm.The algorithm was compared with traditional algorithms to demonstrate the improvement of algorithm performance.
