Abstract: An airborne pulse doppler radar system whose sidelobe clutter amplitude is minimized by providing an antenna whose main beam subtends a small angle and whose radiated energy is concentrated in the main beam and the first few sidelobes and by providing a main beam band rejection filter whose rejection band is closely matched to the antenna main beam clutter frequency band.

Abstract: An umbrella type antenna for delivery and use in space which includes an elongated tube and a cellular panel extending substantially radially of one end of the tube; the panel having support means for holding the panel in a collapsed or closed position during the delivery phase to a desired location and for maintaining the panel radially in an open, position during use, the support means also including a number of support ribs that are pivotally mounted at spaced intervals circumferentially of the tube and at one end thereof; the panel being composed of a plurality of expandable adjacent honeycomb-like cells which cells are disposed in closed condition when the panel is disposed in a closed position on the tube, the cells being disposed in open condition with the panel extending substantially radially outwardly from the tube in the open position, the honeycomb-like cells being formed of interconnected sheets of material which are preliminarily assembled with the cells in the opened positions and the sheets being in tension in the cell-closed condition when the panel is disposed in the closed position whereby the tension sustained in the interconnected sheets forming the closed cells if unrestrained, will cause the panel and ribs to expand from the closed position to the open position, means for releasably holding the ribs and panel in the closed position, each cell containing means for reflecting electromagnetic waves to a focus point on the tubular member, electromagnetic wave-receiving means on the tubular member at the focus point, the whole being coordinated so that the tension-sustained sheets forming the closed cells cause the panel and ribs to expand from the closed position to the open position upon release of the means for holding the ribs and panel in the closed position.
Abstract translation: 一种用于在空间中传送和使用的伞形天线,其包括细长管和基本上在管的一端大致径向延伸的蜂窝板; 所述面板具有支撑装置,用于在输送阶段期间将面板保持在收缩或闭合位置到期望的位置,并且在使用期间将面板径向保持在打开的位置,支撑装置还包括多个支撑肋, 安装在管的周向间隔开并在其一端; 该面板由多个可膨胀的相邻的蜂窝样细胞组成,当细胞被置于处于关闭位置的管上时,细胞处于闭合状态,细胞被置于开放状态,其中面板从 管状处于打开位置,蜂窝状电池由相互连接的材料片形成,这些材料预先与电池处于打开位置并且当电池关闭状态下的片处于关闭状态时被拉紧 由此如果不受限制地形成闭孔的互连片材中的张力将导致面板和肋条从关闭位置膨胀到打开位置,用于将肋和面板可释放地保持在关闭位置的装置,每个单元容纳装置 将电磁波反射到管状部件上的聚焦点,在小管上的电磁波接收装置 在整个焦点处,整体被协调,使得形成闭孔的张力持续的片材在释放用于将肋和面板保持在其中的装置时使面板和肋条从关闭位置膨胀到打开位置 关闭位置。
