舰船用通信网络容易受到敌方电磁场的入侵干扰,导致通信受阻,通过入侵检测,提高舰船用通信网络的抗毁性。提出一种基于自适应线谱增强和滤波技术的舰船用通信网络的入侵检测技术。采用多源波束形成方法进行舰船用通信网络传输信号采集,对采集的通信信号进行自适应线谱增强处理,提高网络通信信号的增益强度,对增强的网络通信信号进行抗干扰滤波设计,采用梯度算法对滤波输出的舰船用通信网络传输信号进行自适应迭代,准确检测出信号中的入侵成分。仿真结果表明,采用该检测技术进行舰船用通信网络的入侵检测的准确检测概率较高,抗电磁干扰能力较强。
Marine ship communication network vulnerable to intrusion of jamming enemy electromagnetic field, resulting in communication is blocked, the intrusion detection system, improve the survivability of marine communication network. Proposed an adaptive intrusion line enhancement and filtering technology based on network communication with ship detection technology. The multi beamforming method for ship transmission signal acquisition and communication the network of communication, signal acquisition of adaptive line enhancement, improve the strength of the signal gain of network communication, anti interference filter design of network communications signal enhancement, using the gradient algorithm of ship filter adaptive iterative communication network transmission signal, accurately detect the intrusion signal components. The simulation results show that the accurate high detection probability with the intrusion detection technology for ship communications network detection, anti electromagnetic interference ability Strong
