对测控扩频通信信号侦察的主动干扰对抗研究

Active Jamming Countermeasures Against TT&C DSSS Signal Reconnaissance

电子侦察对通信与雷达目标辐射源的电磁信息安全构成严重威胁。通过电子侦察自身脆弱性分析,提出对空间电子侦察的主动干扰对抗模型与对抗准则,并就测控扩频通信信号侦察和电子信息防护问题,提出了多种主动有源干扰对抗方法。进一步地,从频域和码域角度分别给出了测控扩频通信侦察的主动干扰对抗理论分析与仿真试验结果。

Electronic reconnaissance poses a serious threat to the electromagnetic information security of communication and radar target radiation sources.In this paper,based on the analysis of the vulnerability of electronic reconnaissance,we put forward the active jamming model and countermeasure criterion of space electronic reconnaissance.Furthermore,the theoretical analysis and simulation results of active jamming countermeasure for TT&C DSSS signal reconnaissance are given in frequency domain and code domain respectively.
