This link should transfer data between Earth and vehicle to provide guidance and observation data, and to permit control of vehicle trajectory and instrumentation through an... View full abstract»

    This paper describes a method of simulating the radar displays of an airborne radar system. The simulator employs a scan-programmed vidicon tube and a low-power light source in conjunction with a three-dimensional terrain model to simulate radar return from land-mass formations, cultural areas, and target complexes. All effects of a moving aircraft, including velocity, heading, altitude, position,... View full abstract»

    This paper describes a delayed-repeater satellite communications system consisting of an orbiting delayed-repeater radio-relay station which passes over terminal ground stations located within the viewing area of the satellite. Messages are exchanged between the satellite and a ground station operating in the 2-kmc band utilizing both polarization and frequency diversity techniques to provide a co... View full abstract»

    The general characteristics of radars using large planar steerable array antennas are discussed. The need for an amplifier for each element is shown, and the tolerances and stability requirements for the amplifiers are discussed. Array geometry, pattern formation and gain, mutual coupling, and beam-steering techniques are summarized. Element minimization and signal-processing techniques are analyz... View full abstract»
