Abstract :
The TOPEX/POSEIDON Project is a joint US and French mission to develop and operate an Earth-orbiting satellite with sensors capable of making accurate measurements of sea level. The NASA radar altimeter (NRA), a fifth-generation US Altimeter, will provide the primary measurement for the TOPEX/POSEIDON Project altimetric mission. The authors present the requirements, altimeter fundamentals, design description, integration and test program, primary elements of ground processing, and assessment for the dual-frequency NASA radar altimeter
