Summary

A K u-band pulsed radar altimeter installed in a satellite can be used to measure instantaneous satellite altitude above the surface of the ocean to high accuracy. Major sources of measurement error can be grouped as follows: radar altimeter, propagation, and ocean surface and geometry. Each group contains random and bias errors. These are discussed and evaluated, the major emphasis being on residual errors that accrue from physical phenomena not under the control of the altimeter designer or user.
