    Consider ¿ as the angle between the beam and boresight of a phased-array radar. A simple explanation is given of the beam broadening along ¿, and in proportion to secant ¿. This leads to a concise consideration of polar sin ¿ space, sine-squared space, and some associated properties. Physical relationships are depicted, without unnecessary mathematical vigor.

    This paper discusses the concept, design, and design verification of the White Sands Range and Range-Rate System. Development of the system has been completed only through the design phase. The system is designed to meet requirements for high-accuracy midcourse tracking under severe target dynamics at the White Sands Missile Range. It is a multistatic Doppler and range tracker which operates at X ... View full abstract»

    Radar measurement and resolution performance, as well as target detection in clutter, depend largely on the transmitted waveform. This explains the sizable effort that has gone into studies of radar waveforms, including attempts at the synthesis of optimum waveforms. This paper shows that, despite the unlimited variety of radar signals, waveform selection is a straightforward process. There are on... View full abstract»

  • Range Sidelobe Suppression for Barker Codes

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1259 KB)

    The utility of Barker-type phase-reversal codes is extended by the use of sidelobe suppression techniques that can be easily implemented in digital form. It is shown that sidelobe suppression techniques can be found where the tapped delay line used to reduce the sidelobes has only a few distinct tap weights, in which case the complexity of the digital processor is greatly reduced. An example is gi... View full abstract»

  • Clutter Performance of Coherent Pulse Trains for Targets with Range Acceleration

    Publication Year: 1971, Page(s):1093 - 1099
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1153 KB)

    The clutter performance of coherent pulse trains is examined when the duration of the pulse train is increased to values for which range acceleration effects must be taken into account. The problem of target detection against a clutter background with differential Doppler is studied in terms of the range acceleration effects on the conventional Doppler response. Specifically considered are the con... View full abstract»

  • On Transient and Periodic Signal Detection in Time-Varying Noise Power

    Publication Year: 1971, Page(s):1100 - 1112
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1985 KB)

    Detectability of periodic and synchronously recurrent transient signals in a noisy environment in which the noise power is time varying is investigated. For at least one noise model, it is shown that the basic nonlinearity of the optimum detector is a limiter. Performance of this optimum detector is compared with analog cross-correlation and clipper cross-correlation (CCC) detectors. It is shown t... View full abstract»

    The problem of scheduling radar tracking pulses in a dense target environment where the position estimation error must be constrained to avoid false return with track correlations is considered. The problem is to schedule n fixed energy pulses such that the rangerate error is minimized at some final time subject to the constraint that the position error will be smaller than some value for the whol...

  • Multipath Angle Error Reduction Using Multiple-Target Methods

    Publication Year: 1971, Page(s):1123 - 1130
    Cited by:  Papers (9)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1665 KB)

    The usual methods of reducing multipath angle errors in monopulse tracking radar achieve only limited success because they do not attack the root of the problem. A more correct approach is to accept the multipath signal as a second target and utilize a two-target signal processor which angle tracks both wavefronts. The processor will decouple the return signals so that relatively interference-free... View full abstract»

  • Drag Measurement in a Low-Density Gas Stream

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2709 KB)

    Two methods of measuring the drag of bodies in a low-density gas stream are described. The supersonic stream had a mean free path as great as 4 cm, and the drag forces were small. A drag balance was adapted from an electrical analytical balance to measure forces up to 70 dynes with less than 1-percent error. With this balance, the drag of spheres was measured for the Knudsen number range from 1.0 ... View full abstract»

  • Comparison of Error Propagation in Local-Level and Space-Stable Inertial Systems

    Cited by:  Papers (15)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1145 KB)

    A comparison of the error propagation in a local-level reference frame is derived for two inertial navigation systems; one has a local-level configuration, and the other has a space-stable configuration. The error propagation is shown to be equivalent for the two cases considered. This equivalence is demonstrated by starting with the error propagation equations for the space-stable system and tran...

  • A New Algorithm for Computing Inertial Altitude and Vertical Velocity

    Publication Year: 1971, Page(s):1143 - 1146
    Cited by:  Papers (19)  |  Patents (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (867 KB)

    Inertial navigators determine inertial altitude and vertical velocity by a closed feedback loop in which the vertical accelerometer output is mixed with a pressure altitude reference. Pressure altitude is determined as a function of presure based on the standard atmosphere models. Since the atmosphere is almost always nonstandard, large inertial altitude and vertical velocity errors may result. A ... View full abstract»

    The design concept for the traveling wave tube amplifier converter for possible use in the Thermoelectric Outer Planet Spacecraft (TOPS) is presented. An unusual combination of semiconductors and magnetics were utilized to achieve very stable voltage regulation on a number of separate outputs to satisfy the requirements of a high-power traveling wave tube (TWT), and at the same time operate at an ...

    The transcalent rectifier can dissipate power losses while rectifying 250 amperes; it rectified 60-Hz alternating current at conduction angles of 180°, 120°, and 60°, and at frequencies varying from 200 to 2600 Hz at a conduction angle of 180°. It was surge-current tested to a peak of 6500 amperes, life tested for 4108 hours, and cycle-life tested for 10 867 cycles while rectifying 250 amperes... View full abstract»

    Many future satellite configurations will require the transfer of signals and power across rotating interfaces. Satellite systems are particularly cost effective for both commercial and military communications applications if their useful lifetime can be demonstrated to be greater than five years. The rotary transformer has the desireable characteristics of high reliability and low noise which qua... View full abstract»

    Power hybrid microelectronic design techniques have been developed to satisfy the requirements of 10-ampere 100-watt series voltage regulators. Application of these new techniques has resulted in a package occupying roughly the same volume as a TO-63 power transistor, yet containing two 30-ampere power transistors, selectable external components, and associated control circuitry.
