对PC雷达的梳状谱干扰技术研究

Research on Comb Spectrum Jamming Technique against PC Radar

为了解决对Pc雷达干扰效率降低的问题，本文利用梳状谱信号即将干扰功率集中在雷达信号频带范围内的部分频率点，对雷达实施干扰，破坏回波信号与参考信号的相关性，从而实现有效的干扰。本文以PC雷达为研究对象，通过仿真，给出了1GHz带宽条件下梳状谱干扰仿真结果，分析梳状谱信号对Pc雷达具有较好的干扰效果，研究成果对Pc雷达干扰装备的研制具有一定的参考价值。

The jamming power was widely spread when a traditional jammer was used to jam the pulse compres- sion radar, and this is a new problem of electronic warfare. To resolve the problem the technique which focuses on the jamming power at part of frequency points within the radar signal frequency band with comb spectrum sig- nals is brought forward in the text. With the focused jamming power the correlation between the echo signals and the reference signals is destroyed and the PC radar is jammed effectively. The simulation results of comb spec- trum under 1 GHz bandwidth are show and an analysis of jamming results that comb spectrum signals jam PC radar is made,which is a benefit to jamming equipment development of PC radar.
