高功率微波对弹载GPS天线的耦合特性分析

建立了高功率微波对弹载GPS天线的耦合模型,仿真分析了高功率微波的脉宽、极化形式及波束与目标的交汇角等因素对耦合特性的影响。研究表明：在采用高功率微波武器攻击GPS制导武器时,为了增大对目标的毁伤概率,可以采用脉宽窄与目标天线极化相匹配的微波源,同时尽量减小攻击波束与弹轴正向的夹角。该研究为高功率微波武器对抗GPS制导武器提供了一定的技术支撑。

Analysis of the Coupling Characteristics of High Power Microwave and Missile-borne GPS Antenna

The coupling model of high power microwave and missile-borne GPS antenna is build up. The effects of pulse width, polarization mode of high power microwave, and angle between the radar beam and target to coupling characteristics are analyzed. The results show that the high power microwave source with narrow pulse and polarization matched with the target antenna should be adopted and the angle between the radar beam and the axis-direction of missile should be decreased in order to increase the probability of damage. The study on the coupling characteristics between high power microwave and missile - borne GPS antenna provides research basis for the confrontation between high power microwave and GPS guided weapons.
