摘要： A measurement system is provided that facilitates the measuring of a shape of a flexible electromagnetic radiation structure. The measurement system includes a plurality of local sensors, a central sensor and a measurement processor. Each of the plurality of local sensors is configured to sense the position of a portion of the flexible electromagnetic radiation structure.

摘要： A reflector for reflecting electromagnetic waves has a configured surface for these waves whereby localized deformations or configurations such as bumps (B) and dents (D) of the reflector (1) are so constructed that the reflector cooperates with several focuses (10A, 10B; 110A, 110B) which are spatially separated from the reflector proper. These focuses are so arranged that the electromagnetic beams emanating from the respective radiators (4A, 4B; 40A, 40B) and are directed onto the reflector can be directed through the reflector onto a common region (3A, 3B) to be illuminated, whereby particularly the beams may be tuned to different frequencies or for operation in different frequency bands. Such reflectors are particularly useful in antenna systems for communications such as satellite communications.

摘要： An improved dual gridded reflector antenna configuration which allows cross-polarization radiation to be scanned in any given direction. The dual-gridded reflector assembly includes a front parabolic reflector illuminated by a first source, and a second parabolic reflector illuminated by a second source. The second reflector is positioned adjacent to and behind the front reflector such that the center points of the reflectors align to define a center axis. Additionally, the first and second sources are positioned at different offsets with respect to the reflectors and have a respective rotated offset angle with respect to the center axis such that the sources define an antenna feed separation. By modifying the offsets and the rotated offset angles, the feed separation can be designed to have an inclination with respect to the north-south or east-west feed separation direction.
摘要翻译：改进的双网格反射器天线配置，允许在任何给定方向上扫描交叉极化辐射。双网格反射器组件包括由第一源照射的前抛物面反射器和由第二源照射的第二抛物面反射器。第二反射器定位成与前反射器相邻并在其后面，使得反射器的中心点对准以限定中心轴线。此外，第一和第二源相对于反射器定位在不同的偏移处，并且相对于中心轴线具有相应的旋转偏移角，使得源限定天线馈送间隔。通过改变偏移量和旋转的偏移角度，进给分离可以被设计成相对于南北或东西方的进给分离方向具有倾斜度。

摘要： An integrated spacing and orientation control system is provided for carrying an array of objects and maintaining a predetermined orientation of the objects and a predetermined spacing between objects. In a presently preferred application, the spacing and orientation system carries an array of anti-mine munitions for clearing a path through a minefield. The invention deploys the anti-mine munitions in a downwardly pointed orientation with proper spacing between munitions, even when the array of munitions is deployed using rocket motors.

摘要： Rear and forward reflector shells or dishes (36,38) are independently supported on a dynamically rigid truss structure (12) by means of separate studs extending from the forward nodes of the truss to the two shells. Forward node (22) carries adjustable rear shell stud (52) and independently carries adjustable forward shell stud (80). Both of the studs have flat portions oriented normal to the radius of the shell so that radial shell expansion due to temperature and temperature differential minimize shell distortion.

摘要： The invention is a system for automatically controlling the surface contour of a deployable and restowable antenna 11 having a mesh reflector surface 26 supported by a circular, folding hoop 12 affixed to a central, telescoping column 14. The antenna 11, when deployed, forms a quad-aperture reflector with each quadrant A-D of the mesh surface 26 shaped to provide an offset parabolic RF reflector.The hoop 12 is supported and positioned by quartz support cords 12 attached to the top 22 of column 14 and by lower graphite hoop control cords 23 that extend between the hoop 12 and base 24 of the column 14. The antenna 11, an RF reflective surface 26, is a gold plated molybdenum wire mesh supported on a graphite cord truss structure that includes the hoop control cords and a plurality of surface control cords 27 attached at selected points on the surface 26 and to the base 24 of column 14. The contour of the three-dimensional surface 26 of the antenna 11 is controlled by selectively adjusting the lengths of the surface control cords 27 and the graphite hoop control cords 23 by means of novel actuator assemblies 56 that automatically sense and change the lengths of the lower hoop control cords 23 and surface control cords 27 to control the contour of the surface 26 of the antenna 11.
