This letter derives the best obtainable sea-surface height measurement precision for the general case of a partially coherent altimeter. Analogous to the Walsh upper bound on pulse repetition frequency for a conventional (noncoherent) altimeter, ther

The precision of sea-surface (or ice-surface) height measurements by radar altimetry improves in direct proportion to the square root of the number of statistically independent waveforms contributing to the measurement average. The closed-burst strat

Conventional quadrature-polarimetric (quad-pol) synthetic aperture radar (SAR) systems operating from space are severely constrained by their limited range of useful incident angles and their reduced swath widths particularly at larger incidence. The

The Altimetric Bathymetry from Surface Slopes (ABYSS), which is the proposed science payload on the International Space Station (ISS), is a Johns Hopkins University Applied Physics Laboratory-developed flight-proved delay-Doppler phase-monopulse rada

Knowledge of sea ice thickness is critical for the prediction of future climate, and for assessing the significance of changes in thickness. Sea ice thickness can be calculated from radar or laser satellite altimetry measurements of freeboard. Howeve

A synthetic aperture radar (SAR) often is constrained to transmit only one polarization. Within this constraint, two aggressive measurement objectives are 1) full characterization and exploitation of the backscattered field, and 2) invariance to geom
