COPY Circular Carrier - Frequency Photography fo ' r Observing Phase Objects
نویسنده
چکیده
A circular grating is photographed through a phase object which deforms the image of the grating lines. By superimposing these deformed lines with a master grating on photographic film, mpire'' patterns are observed. These patterns are interpreted as fringes of constant radial derivative. https://ntrs.nasa.gov/search.jsp?R=19730011754 2017-09-12T18:22:28+00:00Z

Simple and efficient frequency offset tracking and carrier phase recovery algorithms in single carrier transmission systems.
In this paper, we propose a low-complexity and efficient carrier recovery algorithm for single carrier transmission systems that is capable of tracking frequency offset (FO) variations. Working as a FO tracking estimator, the algorithm demonstrates good accuracy in simulation and a FO drift of up to 200 MHz/μs can be compensated with minimal degradation in a QPSK system. In 112 Gb/s dual polari...
متن کاملONE Oscillator Dynamics
A well-designed free-running oscillator provides a periodic signal of constant amplitude and frequency fo from the energy delivered by direct-current (dc) sources. This has an immediate application for the realization of local oscillators used in the frequency-conversion stages of communication systems [1]. In receivers, the modulated signal at radio-frequency (RF) fRF is mixed with the output ...
متن کامل918-t Annual Precise Time and Time Interval (PTTI) Meeting COMPARISON OF ATOMIC FREQUENCY STANDARDS AT NIST AND PTB USING CARRIER- PHASE GPS
We have constructed a link between Physikalisch-Techniche Bundesanstalt (PTB) in Braunschweig, Germany and the National Institute of Standards and Technology (NIST) in Boulder, Colorado using carrier-phase Global Positioning System (GPS) receivers. The link will provide a direct measurement of the frequency difference between UTC(PTB) and UTC(NIST), and can also be used to provide a direct comp...
متن کاملA Time-Domain Method for Shape Reconstruction of a Target with Known Electrical Properties (RESEARCH NOTE)
This paper uses a method for shape reconstruction of a 2-D homogeneous object with arbitrary geometry and known electrical properties. In this method, the object is illuminated by a Gaussian pulse, modulated with sinusoidal carrier plane wave and the time domains’ footprint signal due to object presence is used for the shape reconstruction. A nonlinear feedback loop is used to minimize the diff...
متن کاملLeast Squares Techniques for GPS Receivers Positioning Filter using Pseudo-range and Carrier Phase Measurements
In present study, using Least Squares (LS) method, we determine the position smoothing in GPS single-frequency receiver by means of pseudo-range and carrier phase measurements. The application of pseudo-range or carrier phase measurements in GPS receiver positioning separately can lead to defects. By means of pseudo-range data, we have position with less precision and more distortion. By use of...
