    The need to visualize thermal radiation is outlined. The characteristics of radiant energy and the transmission properties of the atmosphere are discussed to define the spectral range of interest. Practical methods of detecting thermal radiation are reviewed and the benefit of cooling the detector highlighted. Techniques whereby the detector can be made to interrogate the scene are described and c... View full abstract»

  • Formats for digital video tape recorders

    Publication Year: 1982, Page(s):31 - 36
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (749 KB)

    The characteristics required for a studio format digital recorder are considered and variable-speed operation for the Type B and C systems is described. The implication of the picture-in-shuttle techniques are considered and also the reasons for adopting a helical rather than transverse format. Coding systems are then compared in some detail with special reference to error detection and correction... View full abstract»

  • Determination of a.m. cochannel protection ratio for land mobile signals by means of subjective testing

    Publication Year: 1982, Page(s):37 - 40

    An important parameter in the design of mobile radio systems is the co-channel protection ratio. New measurements, based on realistic subjective testing procedures using speech modulation, are presented for the a.m. case. The critical importance of audible carrier interactions is demonstrated. Mean values of protection ratio which were graded by users as `perceptible but not disturbing├é┬┐ decreased... View full abstract»

  • Microprocessor controls for limited-function robots

    Publication Year: 1982, Page(s):41 - 45
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (504 KB)

    This paper describes a microprocessor controller for limited-function, special-purpose robots. Both hardware and software for the controller were developed in modular form so that appropriate modules can be selected to suit a particular robot configuration. Two levels of sequence programming, defining the task to be performed by a robot, can be utilized. Low-level sequence programming can be used ... View full abstract»

  • A survey of planar integrated mm-wave components

    Publication Year: 1982, Page(s):46 - 50
    Cited by:  Papers (7)

    Different approaches for the integration of mm-wave components have been presented recently, suggesting image line or shielded microstrip line for example. A very promising attempt employs quasi-planar structures, like fin-line, and related line configurations for this purpose. The paper gives a survey of various components being developed in the frequency range from 18 to 170 GHz using this appro... View full abstract»
