    A case study demonstrates that spares requirements based on operational reliability predictions result in the system being undersupported during its burn-in and useful-life phases by average factors of 42.2 and 4.22, respectively. However, systems spares requirements based on logistics estimates result in the system being oversupported during its burn-in phase by an average factor of 4.26 with thi... View full abstract»

    Optimum power division is required in deep-space communications links to maximize transmission range or data rate and to permit efficient performance of both carrier tracking and data reception functions. A simple, graphical technique has been developed for phase-modulated links to determine the particular set of peak phase deviations, or modulation indexes, which results in an optimum power divis...

    A radio telemetry system is described which permits the acquisition of aerodynamic data from free-flight models in wind tunnels. Small transistorized telemeters are used. The telemeters are frequency modulated by either variable-capacitance pressure transducers or by variable-resistance heat-transfer transducers.

    Request Permissions | Click to expandAbstract | PDF file iconPDF (4503 KB)  

    In the VKF Counterflow Facility a small test model is launched upstream through the test section flow of a shock tunnel, thus producing relative velocities greater than that of either single component. This facility is presently capable of simulating model velocities greater than 30 000 ft/s (9.2 km/s) and altitudes from 50 000 to 200 000 ft (15.2 to 61 km).

    The determination of the detailed performance of an MHD-augmented high-enthalphy shock tunnel requires the simultaneous measurment of a large number of aerodynamic, electrical, and electromagnetic parameters in a test time interval of the order of several hundred microseconds. In the feasibility study currently being conducted in our laboratory of such a device, an extensive measuring system was s... View full abstract»

    A new resonant quasi-optic interferometer has been developed which has a unique capability to deduce spatial information about perturbing plasma media. The fundamental property of the resonator is that it is multiply degenerate. Its geometry consists of four spherical mirrors arranged in a confocal ring configuration such that the transverse modes are simultaneously resonant. Energy is coupled int... View full abstract»

    This paper considers the signal phase acquisition problem for arrays of large-aperture steerable antennas. In particular, long-range signal acquisition is considered for those cases in which the signal-to-noise ratio in each antenna-receiver channel is too low to permit signal phase-lock in each individual receiver. Techniques are discussed which promise to extend the array acquisition sensitivity... View full abstract»

    Inertial navigation systems usually use gyroscopes to sense angular motion and use accelerometers to sense linear acceleration. It is feasible, however, using only linear accelerometers as sensors, to determine both the angular velocity and the linear acceleration of a vehicle. This paper presents and compares five configurations of linear accelerometers which may be used to determine both the ang... View full abstract»

    In this technique, small blunt models are launched into a mixture of nitrogen and neon in a ballistic range, and the radiation from the shock layer on the forward face of the model is measured during the last few microseconds of flight by a radiometer directly in the flight path of the model. The ultraviolet radiation is sensed with the phosphor sodium salicylate. Comparison with other techniques ... View full abstract»

    The mechanization of a gimballess inertial system for space navigation is considered. An error analysis reveals that the errors contain both sinusoidal and diverging components. Error damping methods are proposed and it is shown that damping can be achieved by using appropriate damping circuits and auxiliary information obtained from devices such as stellar trackers, velocity-measuring optical Dop...

    Another derivation of a continuous-time optimal linear filter is presented. Using this result as a point of departure, a feedback version of this continuous filter is postulated and shown to be optimal in the limit as the ``feedback gain'' becomes infinite. It is then demonstrated that the need for this infinite feedback gain can frequently be eliminated. This feedback realization of the continuou... View full abstract»

    A common problem in waveform design is to adapt the transmitted signal to the target environment in order that the interference from extended fields of scatterers is reduced. This problem is investigated here for the special case of detection of a single target in the ``vicinity'' of an extended clutter space. The paper considers the possibility of confining the matched-filter response in delay an... View full abstract»

    The performance of a uniformly spaced phased-steered line array with element channel superlimiting is studied for far-field sources consisting of 1) two sinusoidal signals with different frequencies and angular locations, and 2) a sinusoid and a noise signal at different angular locations. Attention is focused on the nonlinear case where internal noise is negligible compared to both input signals.... View full abstract»

    This paper describes a system of navigation by measurement of the Doppler shift in the radio transmissions from a near-Earth satellite, and simple equipment for making the measurements. It also shows that the current information which is needed by the navigator can be reduced to a number containing six decimal digits.

    The nonstationarity of the low-frequency radar echo envelope observed from an aircraft is shown and a simple model of the echo is suggested. This model, devised specifically for simulation studies using computers, reproduces the characteristics of the observed envelope, demonstrating the correlation between the observed nonstationarity and aircraft motion relative to the receiver.
