ERS-1 radar altimeter system performance evaluation and calibration
Abstract
The ERS-1 (ESA) radar altimeter system simulation philosophy and simulator development are described. The simulator models system geometry, echo process, uplink/downlink, platform characteristics, instrument processing, ground processing, system errors, and special target characteristics (e.g., reflections from ice surfaces). It supports pre and post launch system-calibration; refinement of the engineering specifications during the ERS-1 development phase; monitoring and controlling of instrument design and development; prelaunch verification of system performance; investigation of inflight malfunctions and compensation of errors during nominal operations; development of echo models; and demonstration of system capabilities in operational cases.
