In GPS measurement, the existence of cycle slip directly affects the ultimately positioning accuracy. In order to obtain high positioning accuracy, cycle slip in carrier phase observations must be detected and repaired. So detecting and repairing of cycle slip has become one of the most important parts of GPS phase data processing. This paper presents our investigation of the cycle slip detection...
In airborne/stationary bistatic-synthetic-aperture-radar imaging, translational invariance was no longer valid. After range cell migration correction, the range-compressed signal under the same range gate exhibited azimuth-dependent FM rates that made the motion-induced phase error difficult to separate from the echoes. To solve this problem, an azimuth-dependent phase gradient autofocus (PGA) algorithm...
