    The 30+ year development of random signal radar (RSR) is described in this paper. Conventional methods of implementing RSRs are summarized: correlation, spectrum analysis, and anti-correlation. Some typical RSR systems are introduced; for example: noise frequency modulation continuous wave radar; and random binary phase-coded continuous wave radar, and their merits and demerits are also pointed ou...

  • A (design-oriented) reliability model for active phased arrays in satellite communication systems

    Publication Year: 1997, Page(s):23 - 29
    Cited by:  Papers (3)

    This paper proposes a modeling approach to relate the power section reliability of satellite payloads to the on-board antenna complexity. The aim of the model is to support the development of design tools for satellite systems adopting active phased arrays. The achieved results are rendered parametric with respect to a key system requirement, the effective isotropic radiated power, due to its dire... View full abstract»

    In the past, functional test requirements (FTR) or test requirement documents (TRD) and test program sets (TPS) were standalone items developed by individual engineers. In some cases, one engineer would write the FTR/TRD and another would develop the TPS. Commercial ATLAS FTRs are prepared in ARINC 616 and 626 ATLAS. Military TRDs are written in IEEE ATLAS 716 versions. Previous test reuse attempt... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (528 KB)

    Advanced communications, guidance and navigation systems play key roles in determining superiority of one combat aircraft over another. The use of advanced technology is essential to meeting the mission requirements of present as well as future aircraft. Modular avionics are being used in next generation aircraft, such as the Air Force F-22 fighter and the Army Comanche helicopter, as the means of... View full abstract»

  • Life cycle testing of a sealed 24-V, 42-Ah nickel-cadmium aircraft battery

    Publication Year: 1997, Page(s):17 - 22
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (464 KB)

    Extensive research has been conducted in the design and manufacture of very long life sealed maintenance free nickel-cadmium aircraft batteries. This study presents data on a 100% depth of discharge (DOD) life test performed on a nominal capacity 42-Ah battery. The purpose of this study is to validate design concepts, determine the life characteristics of the newly designed sealed Ni-Cd batteries,... View full abstract»

  • Conception of spacecraft centralized power supply

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (360 KB)

    A reliable power supply for spacecraft is one of the central problems determining the future development of space technology. The traditional solution to this problem implies having an autonomous power plant on board each spacecraft. The most widely used are power plants with solar cells. However, there exists an alternative power supply concept of using a centralized power supply system (CPSS) an... View full abstract»

  • Experiments with numerically controlled atomic clocks

    Publication Year: 1997, Page(s):8 - 11
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (296 KB)

    Long term timing stability of present atomic clocks can be considerably improved by simple numerical algorithms which correct both the inherent frequency bias and the effects of supply voltage variations and outside temperature. Rubidium units are demonstrated to operate with less than 100 ns errors per week or any sensible longer interval corresponding to relative uncertainties of 10-13 View full abstract»
