Wet Tropospheric Correction Methods for Wide-Swath Altimeters
IEEE Transactions on Geoscience and Remote Sensing, 2022Wet troposphere path delay (WPD) is a crucial error source for wide-swath altimeters with high-resolution observations. This study generated a simulated wide-swath through the nadir microwave radiometer (MWR) track and evaluated four wide-swath wet ...

Site selection for the validation of wide-swath interferometric altimeter in the South China Sea
International Journal of Remote Sensing, 2022Altimetry is widely used in the research of oceanic phenomena. Particularly, wide-swath interferometric altimetry (WIA) can be used to measure sea surface height (SSH) with sufficiently high resolution. Although it has provided that the steric height can

The wide-swath altimeter uses interferometric synthetic aperture radar technology to obtain a wide-swath detection capability. Referable to the slow undulation of the ocean surface, flat-earth phase is dominant in the interferometric, and the interferometric phase after flat-earth phase removal can reflect the ocean surface elevation change.

Wide swath SAR and radar altimeter
1993 IEEE Aerospace Applications Conference Digest, 2002The conceptual design and a spaceborne, high-resolution, wide-swath synthetic aperture radar (SAR) and radar altimeter that can be implemented in L, C or X-band or in a combination of bands is described. The design uses active planar array antennas to form multiple independent beams that cover swaths of up to 700 km.
