HADR天线是为高功率S波段三座标雷达系统而设计的一种平面阵列天线。它在仰角上采用相扫,在方位上则采用360°机械扫描。为了获得最佳的数据率和最佳的能量控制,仰角上的电波束宽度是这样控制的:在低仰角为笔形波束而在高仰角使波束加宽。天线由缝隙波导阵列组成,其水平波束具
The HADR antenna is a planar array antenna designed for high power S-band three-coordinate radar systems. It uses a phase sweep at elevation and a 360 ° mechanical scan in azimuth. For optimal data rates and optimum energy control, the beam width at elevation is controlled such that the pencil beam widens at high elevation angles at low elevation angles. The antenna consists of a slotted waveguide array with horizontal beams
