Resolution of Ambiguity in Derivation of Pseudopotentials from Phase Shifts

Physical Review Letters, 1971
In fitting electronic band structures of solids by means of scattering phase shifts, the level of the "muffin-tin" potential can be chosen at will relative to the Fermi level. Different choices correspond to distinct ways of expressing the total valence-electron density as a sum of atomic contributions.

Single receiver phase ambiguity resolution with GPS data

Journal of Geodesy, 2010
Global positioning system (GPS) data processing algorithms typically improve positioning solution accuracy by fixing double-differenced phase bias ambiguities to integer values. These “double-difference ambiguity resolution” methods usually invoke linear combinations of GPS carrier phase bias estimates from pairs of transmitters and pairs of receivers,

Phase direction finder ambiguity resolution

Radioengineering
Modern phase direction finding means, in particular passive direction finding means, must ensure the formation of direction finding data from radar sources, while the bearing accuracy must be maintained over a wide frequency range. As is known, in order to achieve high accuracy of direction finding, the distance between the receiving antennas must ...

Resolution of phase ambiguities in electron-impact ionization amplitudes

Physical Review A, 2003
The formal theory of atomic ionization by electron impact relates the breakup amplitude to an integral expression involving the exact wave function and an unperturbed final state that contains two Coulomb functions with effective, noninteger charges. This integral expression has an associated phase factor that diverges logarithmically on an infinite ...

Carrier Phase Integer Ambiguity Resolution

2017
Global Navigation Satellite System (GNSS ) carrier-phase integer ambiguity resolution is the process of resolving the carrier-phase ambiguities as integers. It is the key to fast and high-precision GNSS parameter estimation and it applies to a great variety of GNSS models that are currently in use in navigation, surveying, geodesy and geophysics.

Resolution of a phase ambiguity in a calibration procedure for polarimetric radar systems

IEEE Transactions on Geoscience and Remote Sensing, 1994
A cross-pol/co-pol phase ambiguity in a previously published calibration procedure for polarimetric radar systems is discussed. The original procedure is modified to resolve the ambiguity while still retaining insensitivity to calibration target orientation.

Ambiguity resolution for dual frequency carrier phase kinematic GPS

2004 IEEE Region 10 Conference TENCON 2004., 2004
In this paper, the kinematic GPS positioning method for dual frequency (L1 and L2 bands) observations is presented by applying the Kalman filter. And the method is examined by using real receiver data. As a result, if the baseline length is short, the method can resolve the integer ambiguity much faster than using only single frequency data. The method

Statistical GNSS carrier phase ambiguity resolution: a review

Proceedings of the 11th IEEE Signal Processing Workshop on Statistical Signal Processing (Cat. No.01TH8563), 2002
Global Navigation Satellite System carrier phase ambiguity resolution is the key to high precision positioning and navigation. In this contribution a brief review is given of the probabilistic theory of integer carrier phase ambiguity estimation. Various ambiguity estimators are discussed.
