    The delay-lock discriminator is a statistically optimum device for measuring the delay between two correlated waveforms. Its theory of operation and the performance of an experimental model have been described by Spilker and Magill.1 The application of this device to range-and angle-measuring systems is discussed herein. Utilization of the delay-lock discriminator can lead to substantia... View full abstract»

    The synchronizing performance of a phase-lock loop, in the absence of noise, is obtained by replacing the sinusoidal characteristic of the product demodulator, as a function of phase difference, by a triangular piecewise linear approximation. The analytical conditions for existence of a limit cycle (steady-state asynchronous mode) with a steady input frequency are derived. They may be solved numer... View full abstract»

    This paper analyzes the various types of continuous wave and pulse modulation for the transmission of sampled data over channels perturbed by white Gaussian noise. Optimal coherent synchronous detection schemes for all the different modulation methods are shown to belong to one of two general classes: linear synchronous detection and correlation detection. The figures of merit, mean-square signal-... View full abstract»

  • Clock Sources for Synchronized Communication Systems

    Publication Year: 1962 , Page(s): 23 - 30

    The ideal clock source will have start-stop capability, maintain known phase with respect to a start signal and combine high-frequency stability with voltage tuning to permit phase lock and Doppler correction. These properties define a clock source suitable for synchronized communication systems in which a remote unit must be started in synchronism with the signal received from a local unit. For s...

    The purpose of this paper is to create greater familiarity with recent developments in Luneberg lenses and to point out their usefulness in space communications. The term Luneberg lens is widely used to denote any lens having a radial variation in index of refraction. As a result of the radial variation in index a Luneberg lens antenna may scan a full 3600 by feed movement alone or simultaneous co... View full abstract»

    This paper presents formulations which relate average received signal power, noise density, and bit rate of the to source to the expected probability of bit error in the received information for binary phase modulation systems. The performance of these systems is analyzed for the practical case of demodulation with switching-type phase detectors and the performance is compared with optimal product... View full abstract»

    The Blue Scout, Jr. is a sounding rocket which will be instrumented to measure various forms of radiation at altitudes up to 100,000 miles. Space-General Corporation has built a Digilock telemetry system to convey the radiation information from the vehicle to the earth. The telemetry flight-unit communicates twenty 5-bit digital inputs, encodes the selected words into one of a family of binary ort... View full abstract»

  • The Nature of Astro Doppler Velocity Measurement

    This paper deals with astro Doppler velocity measurement for space vehicle navigation. The measurement yields the relative velocity of the vehicle with respect to a star, and requires the use of electro-optical systems capable of measuring a small incremental change in the wavelength of propagated stellar energy. Such systems provide velocity data whose character and limitations are a function of ... View full abstract»

    With the exception of those systems which are intended to satisfy special military requirements, passive satellite communication systems will not be economically competitive with high-capacity, active satellite systems because of greater terminal costs. There are twelve reasons why stationary orbit systems should become the backbone of future global communications, and these are discussed in detai... View full abstract»
