Interferometric GPS ambiguity resolution

Journal of Engineering Mathematics, 2002
The Maximum a Posteriori Ambiguity Search (MAPAS) method for GPS (Global Positioning System) ambiguity resolution first introduced by Macabiau, is generalized to accommodate: (1) satellite switches caused by satellites rising or falling below the horizon or obstructing terrain, and (2) cycle slips due to temporary loss of lock on satellite signals.

Ambiguity resolution for permanent scatterer interferometry

IEEE Transactions on Geoscience and Remote Sensing, 2004
In the permanent scatterer technique of synthetic aperture radar interferometry, there is a need for an efficient and reliable nonlinear parameter inversion algorithm that includes estimation of the phase cycle ambiguities. Present techniques make use of a direct search of the solution space, treating the observations as deterministic and equally ...

Multiple target ambiguity resolution

Proceedings of 1994 IEEE National Radar Conference, 2002
The Chinese remainder theorem is usually used to resolve ambiguities for both high-PRF and medium-PRF pulse-Doppler waveforms. In a previous paper it was shown that superior results for a single target can be achieved by using a clustering algorithm. In this paper the problem of multiple targets is considered.

Resolution of interferometric ambiguities

IEEE Antennas and Propagation Society International Symposium. Transmitting Waves of Progress to the Next Millennium. 2000 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.00CH37118), 2002
A new technique is described to resolve the ambiguities of wide field of view interferometers. The use of integer fractional baselines minimizes the number of additional elements since the ambiguities of the smaller baseline straddles those of the overall baseline.

Ambiguity Resolution in Interferometry

IEEE Transactions on Aerospace and Electronic Systems, 1981
A comprehensive theory of interferometry from a system viewpoint with particular emphasis on the ambiguity resolution problem is developed. The derived error equations include contributions from all system uncertainties, i.e., phase measurement, frequency, and element phase center position errors in three dimensions. The direction-of-arrival errors are
