【摘要】 本文介绍了一部机动式高功率自动折叠单脉冲赋形反射面天线。本天线采用过模圆波导实现兆瓦级高功率传输,馈源采用高效率单口多模单脉冲馈源,并针对高功率进行优化设计。反射面天线设计过程中,通过改进赋形方法计入馈源相位方向图的影响,从而改善了天线的聚焦效果。为满足机动式运输要求,反射面天线的主面通过液压机构可自动折叠展开,副面可自动升降。试验表明本天线可承受1.2MW的峰值功率,且具有高效率、高精度、机动性好的优点。更多还原

【Abstract】 A maneuverable monopulse reflector antenna is described in this paper.Over-mode circular waveguide is utilized in this antenna to transfer megawatt high power.A single aperture multimode monopulse feed is adopted which has optimized to sustain high power.In designing the reflector antennaIphase pattern of the monopulse feed is reckoned in by an innovative shaping method,which improves the focusing effect.To meet the requirement of maneuverability,ty using a hydraulic systemithe main reflector can fold and unfold automatically,and the sub reflector can rise and fall automatically,too.Experiment results show that this antenna can endure 1.2 megawatt peak power,and it has the advantages of high efficiency,high precision and good mobility.更多还原
