    Engineering schools have a responsibility to provide a science background upon which graduates may build to solve the across-the-discipline challenges of tomorrow. They cannot and should not train for solutions to today's problems. Schools must insure that their faculty continues its education beyond the Doctor's degree by means of workshops, professional meetings, and involvement in investigation... View full abstract»

    The array approach to increasing space-communication capability is analyzed and discussed. The problem of signal acquisition is given particular attention. A lower range bound of array operation is defined by assuming a system which employs independent acquisition by each antenna circuit; an upper bound is defined by assuming a prefocused array. It is believed that systems can be implemented which... View full abstract»

    A two-port with both generator and load constitutes a closed system; it can be defined as a system with only interdependent variables or as a system containing no independent variables. The flowgraph describes the relationships between variables in a closed system as determined by the topology of its components. The corresponding closed flowgraph represents a zero-port network from which N-port ne... View full abstract»

    For many military applications, low-frequency oscillators are required which maintain their frequency within 5 parts in 104 after they have been exposed to an acceleration of 30 000 g and also after a storage period of 5 years. In addition, the same stability must exist while a constant acceleration of, say, 5000 g is applied. The characteristics of mechanical systems and various electrical circui... View full abstract»

    Secure ground-to-ground communication links, communication from satellites and space probes, and coherent optical logic in high-speed integrated computers lie within the realm of semiconductor single lasers or laser arrays. Lasers of this type have the advantage of extremely small size, ease of direct modulation, and high efficiency. Ruggedness and simplicity of pumping promise high reliability fo...

    A method of improving angular discrimination artificially in radar beacon systems, without going to extremely high frequencies of operation or using unreasonably large interrogator antennas, involves the use of a null-type antenna pattern superposed on a normal directional beam. The effective are over which replies are obtained is determined by an amplitude discriminator circuit within the beacon ... View full abstract»

    The use of a two-lobe monopulse radar for measuring slant range to the surface of the earth in the absence of discrete targets is analyzed. It is shown that tracking dispersion can be considered as the resultant of two components. One component is independent of range and results from the finite pulse length and gate length and the random nature of the return signals. The other component is due to... View full abstract»

    Aircraft maintenance has, since its conception, relied primarily on two methods of fault detection and isolation: 1) in-flight observation and reporting by flight personnel 2) ground operation or testing of airborne systems and equipment. Both methods, even when combined to the optimum, are not always sufficient to pinpoint the exact cause of trouble or locate a defective component. A third method... View full abstract»

    A height-finding technique utilizing the relative phase between a series of point sources of a traveling-wave array is described. The point sources in the focal region of a torus antenna are used to control the phase of the antenna elevation pattern in space. Signals received from a given beam angle will arrive at each terminal of the traveling-wave feed with a different phase. By comparing this p... View full abstract»

    Discoloration of ZnO from ultraviolet absorption can be produced in the laboratory, but is most severe in extraterrestrial environments, when microcrystalline ZnO is used as a pigment for spacecraft thermal control surfaces. Understanding of this degradation process should lead to development of pigments with improved thermal stability under prolonged ultraviolet exposure. It is noted that movemen... View full abstract»

    This paper presents the theoretical probability densities of the outputs of both an amplitude-comparison monopulse radar and a phase-comparison monopulse radar when the monopulse radars are excited by Gaussian signals plus Gaussian noises. These probability densities are useful for studying the responses of monopulse radars to noise excitations. For example: Noise excitations arise when the monopu... View full abstract»
