基于叠加扩频频谱中心技术的抗欺骗干扰研究

Research on a method of center of spreading spectrum testing deception jamming

针对机载多天线收发系统(Multiple Input Multiple Output,MIMO)面临存在虚假指令的欺骗干扰威胁导致性能下降甚至失锁问题,提出了一种基于叠加扩频频谱中心技术检测欺骗干扰方案,最后通过试验验证了该方案的可行性,对MIMO抗虚假指令欺骗干扰性能的提升具有实际意义。

According to the problem of performance reduction even losing lock for the MIMO system threatened by deception jamming with pseudo-command,this paper presents a technology can test the deception jamming based on central part of spreading spectrum.And this method realizes the deception interference prevention.Finally it verifies the feasibility by experiment,which is importance to promote the capacity of resisting deception jamming.
