A Brief Investigation into the Validity of SEASAT Radar Altimeter Data Acquired Over Land.

Abstract

The SEASAT 1 satellite, which was launched in 1978, carried a radar altimeter which was optimized for operation over the open ocean. However, the instrument did make a significant number of measurements while over land. It is conclusively demonstrated that the radar altimeter serendipitously made measurements over relatively flat terrain which can provide accurate ground elevations. In addition, it is possible that the instrument had some capability to distinguish ground features such as canals, elevated roads, and power lines.
