无载频超宽带雷达的梳状谱干扰仿真研究

超宽带雷达的发展及其在军事上的应用,对传统雷达对抗装备提出了严峻的挑战,极宽的信号带宽迫使干扰信号在频域上分散,从而大大降低了干扰信号的有效性.为了集中信号功率,对超宽带雷达进行有效干扰,提出了梳状谱干扰技术,即将干扰功率集中于雷达信号带宽范围内的一些离散频率点实施干扰,破坏雷达回波信号与参考信号的相关性,从而实现有效干扰.以无载频超宽带雷达为研究对象,通过仿真方法,将梳状谱干扰与传统的噪声干扰进行比较,得出梳状谱干扰技术对无载频超宽带雷达具有明显的干扰效果.研究成果对超宽带雷达干扰装备的研制具有一定的参考价值.

Jamming the Carrier-Free Ultra-Wideband Radar with Comb Spectrum Signals

The traditional radar jamming equipments have been challenged by the Ultra-Wideband (UWB) radar, which is developed quickly and used widely in both military and civil areas. In order to jam the UWB radar, the jamming power must be spread to as wide as the radar signal. And in this way the jamming power is not effective any more. For focusing the jamming power the paper brings forward a new technique that jams the UWB radar using the comb spectrum signals. That is to focus the jamming power to some frequency...
