摘要： An apparatus and method for testing of rotating surface based antennas arrays (regardless of their shape), with the capability of fully diagnosing and locating a failure on the face of the antenna by coherently sampling and storing the radiation in the near field and imaging the fully array complex excitation from the stored data. The rotation of the antenna is used in order to collect data for the full azimuth span required for high resolution imaging of excitation in the horizontal domain. Excitation in the vertical domain can be preformed in two ways depending on the type of antenna used. For electronically scanning antennas in elevation (phased array antennas), the phase shifter in the desired row is toggled and the row is isolated by subtracting the complex data from pairs of adjacent samples. The sampling probe is moved vertically while the antenna is rotating horizontally. The vertical movement of the probe provides the aperture necessary to resolve the vertical excitation of the array to a degree of accuracy sufficient for fault detection and isolation.

摘要： The satellite selection method as utilized by the spaceborne Global Positioning System receiver provides navigational solutions and is designed for use in low Earth orbit. The satellite selection method is a robust algorithm that can be used a GPS receiver to select appropriate GPS satellites for use in calculating point solutions or attitude solutions. The method is takes into account the difficulty of finding a particular GPS satellite phase code, especially when the search range in greatly increased due to Doppler shifts introduced into the carrier frequency. The method starts with an update of the antenna pointing and spacecraft vectors to determine the antenna backplane direction. Next, the GPS satellites that will potentially be in view of the antenna are ranked on a list, whereby the list is generated based on the estimated attitude and position of each GPS satellite. Satellites blocked by the Earth are not entered on this list. A second list is created, whereby the GPS satellites are ranked according to their desirability for use in attitude determination. GPS satellites are ranked according to their orthogonality to the antenna backplane, and according to geometric dilution of precision considerations. After the lists are created, the channels of the spaceborne GPS receiver are assigned to various GPS satellites for acquisition and lock. Preliminary Doppler frequencies for searching are assigned to the various channels.

摘要： Scanning apparatus which scans input radiation from a scene and output radiation is transmitted to a receiver system, for example a millimetre wave imaging camera or a radar receiver by a rotatable reflective plate having an axis of rotation passing through the centre of its surface, secondary reflector and static reflector, wherein the secondary reflector is a second rotatable reflective plate having a common axis of rotation with the first rotatable reflective plate, wherein the common axis of rotation is inclined at a non-zero zero angle &thgr;b to the normal to the second reflective plate. The normal to the first rotatable plate is inclined at a small angle to the common axis of rotation, typically a few degrees and forms the secondary reflector. The static reflector may be a polarising roof reflector through which radiation is input to and output from the apparatus. The apparatus also includes a 45° Faraday rotator or a birefringent surface such as a Meander-line. An additional Faraday rotator and an inclined polariser may be included in the apparatus and arranged such that radiation output to the receiver system may be separated from the path of input radiation. Alternatively, the scanning apparatus may include a reflector lens arrangement, such that focused output radiation may be output directly to the receiver system.

摘要： An object shape distribution of an antenna intergral-type communication device to be observed with a sensor for measuring a three-dimensional shape is measured and recorded, and a scanning distribution of an interference complex data between a detected signal with a scanning probe antenna measuring a two-dimensional distribution of an electromagnetic wave and a detected signal with a fixed probe antenna, a relative position of which does not change against a measured object, as a two-dimensional electric field distribution or a two-dimensional magnetic field distribution is measured and recorded, based on movement with a predetermined step as a minimum movement unit. The object shape distribution and the two-dimensional electric field distribution or the two-dimensional magnetic field distribution are displayed in a superimposed state on a screen. A line area and a plane area of the antenna integral-type communication device are specified for the display screen. A complex current distribution of the specified line area and plane area is derived from the object shape distribution and the two-dimensional electric field distribution or the two-dimensional magnetic field distribution. Directivity is derived from the object shape distribution and the complex current distribution of the line area or the plane area. The derived directivity is displayed.

摘要： A system and method for eliminating pointing error in a beacon tracking system due to uncontrolled differences in passive loss or in amplification of the separate signals involved in creating a pilot signal. A locally generated reference signal (30) is radiated onto a set of feed horns (14), at least three (20, 22, 24) of which are used to track a pilot signal (18). The reference signal (30) is detected and used in an automatic gain control feedback loop (44, 46, 48) to maintain equal gain on the separate feed horn channels. The equalized signal is processed (62) to produce precision tracking signals.

摘要： A positioner (or gimbal assembly) for a compact antenna assembly is disclosed. The positioner provides accurate pointing of the antenna assembly (typically a narrow beam radio frequency (RF) radiating assembly) mounted on a rapidly moving platform. The positioner is comprised of a first, second, and third axis assemblies which support the antenna assembly and allow rotation of the antenna assembly about first, second, and third axis. The axis assemblies are arranged so the first, second and third axis are non-orthogonal and intersect at the approximate geometric center of the antenna assembly allowing continuous and independent rotation of the antenna assembly about each axis within a confined volume.
