摘要
为了分析电子对抗无人机飞行姿态对其机载干扰天线干扰效能的影响,推导了其干扰天线的干扰极化特性随飞行姿态的变化规律,计算了不同侧飞倾角时的垂直极化分量的空间分布。结果表明,侧飞有利于增强对垂直极化天线的干扰效果。
The flight attitude of unmanned air vehicle（UAV） has effect on jamming effectiveness of jamming antenna. In order to analyze the effect, the formulae of the vertical polarization electric field radiated from jamming antenna were deduced. The spatial distribution of vertical polarization component corresponding to different slope angles was calculated. The results show that slanting flight can improve the UAV＇ s jamming efficiency for vertical polarization antenna on the ground.
