    There are two main parts to an antenna or RCS measurement system: the measurement instrumentation, and the measurement environment or `range'. The performance of the measurement system is dependent upon both the instrumentation and the range. Developing a successful measurement system requires understanding both parts of the system. The paper describes a compact test range that has been designed a... View full abstract»

    As satellites and their payloads become more complex, the means by which the in-orbit performance can be verified on ground also become more complex. This is particularly true for radiating payloads where the satellite itself is a part of a complex system comprising ground, in-orbit and ground/sea/air segments. The paper describes the Estec compact payload test range which has been developed to al... View full abstract»

    The compact range mechanically collimates electromagnetic energy, thus creating a plane wave useful for testing antennas in a far field environment. Since this collimation can be achieved in a relatively small space, the tests can be performed in an environmentally controlled chamber. With the increasing use in both military and commercial applications of antennas operating at millimeter wavelengt... View full abstract»

    The antenna laboratory of Queen Mary and Westfield College is now operating a new compact Antenna Test Range (CATR) facility. The associated reflector is made of 18 panels each with surface accuracy of about 10-18 μm RMS, which makes the range operational for frequencies in excess of 200 GHz. Practical experience gained during measurements of antenna patterns at 183 GHz revealed that the gap fo... View full abstract»

    A compact antenna test range (CATR) was established at Marconi Command and Control Systems Ltd, Frimley, in the autumn of 1987. The majority of the equipment was of proprietary origin. Its first principal role was the measurement of a high gain precision radar tracking antenna designed for operation within the 33 to 36 GHz frequency band. It soon became apparent that the interaction between the CA... View full abstract»

  • Millimetre wave application up to 204 GHz of the compensated compact range

    Publication Year: 1991, Page(s):3/1 - 3/7
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (312 KB)

    The measurement of the characteristic antenna data by means of conventional far-field test ranges in frequencies around 200 GHz requires measurement distances of up to some kilometers. The compact antenna test range is a high precision test facility developed by and installed at MBB that has got a quiet zone of 5.5×5.0×6.0 m. This new measurement concept is quasi-optical and consists o... View full abstract»

  • Practical considerations in selecting software or hardware gating for RCS measurement systems

    Publication Year: 1991, Page(s):10/1 - 1011
    Cited by:  Papers (1)

    As in any real world measurement application, there are performance trade offs to be made between hardware and software gating in RCS measurements. Hardware gating adds significant complexity and cost to the measurement system and, incorrectly applied, can result in degraded measurement performance. A measurement system based on software gating is the simplest and most cost effective to implement ... View full abstract»

  • Design of an array antenna for a UHF compact range

    A design of such an antenna was developed in an earlier project by Wong and Excell (1989) at Bradford University, using a hexagonal array of seven log-periodic dipole antennas. A numerical model for the array, based on the NEC program, was developed and used with a near field synthesis program based on the regularisation methods of Mautz and Harrington (1975). The antennas chosen for experimental ... View full abstract»
