Jamming the LFM-UWB Radar with Comb Spectrum Signals
Qiuxi Jiang · Modern Defence Technology · 2008
The jamming power was widely spread when a traditional jammer was used to jam the ultra-wideband radar.And this is a new problem of electronic warfare.To resolve the problem the technique which jamming the UWB radar with comb spectrum signals was brought forward in the text.That is to focus the jamming power at some frequency points between the radar signal bandwidth.With the focused jamming power the correlation between the echo signals and the reference signals was destroyed and the UWB radar was jammed effectively.The simulations of the range profile of the LFM UWB radar under different conditions was showed in the text.The results show that the jamming technique is effective to the LFM UWB radar.
