    The characteristics of the radar system are described. Its main features are the use of the frame mode of operation to widen the swath and employment of a common antenna for all three wavelength bands. The radar meets the requirements for its intended applications for scanned observation covering a swath width of several hundred kilometers when resolution is approximately 50 m. Radar images of cer... View full abstract»

    The key elements of a noncommercial computerized flight inspection system designed for testing of basic air navigation ground facilities are described. Choice of proper power supply, connection of different receivers, their characteristics, antenna installations and data processing algorithms are discussed in detail. Aircraft ground tracking techniques are considered together with achievable posit... View full abstract»

    The use of ultra-wideband (UWB) radar to solve the problems of measurement of coordinates and their derivatives, discrimination and radar imaging, and measurements of radar target characteristics, which occur in radar target observation, is discussed. The signal model used for UWB signals is examined. Scattering, formation reception of signals, and digital processing techniques are considered.< View full abstract»

    The making of UDFs (user data files), which are loaded into electronic warfare devices on tactical aircraft, is considered a simple case of a flexible manufacturing system. The UDFG (user data file generator) for the ASPJ (airborne self-protection jammer) consists of a set of database and text editing routines to incorporate entries concerning threat data, countermeasures options, and aircraft-dep...

    Fault tolerances of a triple flight control architecture are defined and compared to that of a quadrupole type, and the impact of worst case failures on the transient response of an aircraft is investigated. Insights in computing fault coverage are discussed. Two coverage models have been used to compute the probability of loss of control (PLOC) and the probability of mission abort (PMA) for candi...

    Fault-tolerant electrohydrostatic actuator (EHA) architectures have been defined and evaluated for future military aircraft applications. The fault tolerances of these EHA architectures have been measured in terms of mission success probability and safety reliability. The functional level failure modes of an EHA and its interfacing equipment are used to analyze the required levels of redundancy an... View full abstract»
