基于截取交织的GPS污染谱干扰技术

提出了一种新式拦阻式干扰——"污染谱"干扰,用于干扰GPS接收机。分别提出了基于截取交织技术的等间隔等脉宽与非等间隔非等脉宽"污染谱"干扰产生方式,对其频域特性与干扰效果作了理论分析与仿真实验。仿真结果表明,适当选取"污染谱"干扰的分段数与脉宽,尤其是非等间隔非等脉宽情形下,可以达到优于扫频干扰与离散梳状谱干扰的干扰效果。

GPS Smeared Spectrum Jamming Technique Based on Chopping and Interleaving

A new blocking jamming technique for GPS receiver jamming-smeared spectrum was proposed.Two generating methods of smeared spectrum jamming based on chopping and interleaving,one has equal sub-pulse width and equal interval and another has unequal sub-pulse width and unequal interval,were proposed.The characteristics of the smeared spectrum in frequency domain and the jamming effect on the GPS receiver were analyzed and simulated.The simulation results show that the new jamming technique has better jamming effect than frequency sweeping jamming and discrete comb spectrum jamming if the sub-pulse widths and the intervals are selected carefully.
