Timeliness of Correcting Baseline Error in Wide-Swath Altimeter Based on Reference Topography Data
Remote Sensing, 2023 The baseline error is a primary error source of the wide-swath altimeter, directly related to the cross-track distance, and can lead to serious height errors at the swath’s outer edge.
