Abstract
This paper provides a study of robust TOA discriminators used in ground-based retracking of a space-based altimeter da-ta. Requirements to an on-board TOA tracking loop are limited to reliable locking of received echo-signal within the tracking window, while fine measuring of altimetry parameters (orbit height, SWH, etc.) is a task of the Earth-based retracking. In the robust algorithms TOA-measuring is performed without using any echo physical model. It can improve space-based altimeter operation near the coastline where terrain areas falling into the illuminated spot distort the received signal significantly versus the one from the “pure” water surface. Analyt...
