摘要

两个X/Ka三波段反射天线(大型X/Ka和小型X/Ka)已经为海军多波段终端(NMT)计划设计、制造并成功测试。这两种系统都通过了DVT测试,性能优异,并且已经交付了几台EDM设备。提出了设计的关键挑战,包括紧凑的低轴比三带馈电,高效率和低副瓣的反射光学。在DVT和EDM装置上取得了良好的测量结果。

NMT X/Ka tri-band antennas
Two X/Ka tri-band reflector antennas (Large X/Ka and Small X/Ka), have been designed, fabricated, and tested successfully for the Navy Multiband Terminal (NMT) program. Both systems have gone through DVT tests with excellent performance and several EDM units have been delivered. Key challenges of the design are presented, including a compact tri-band feed with low axial ratio, reflector optics with high efficiency and low sidelobes. Excellent measured results have been obtained for DVT and EDM units.
