ERS-1, the European Remote-sensing Satellite, carries an Active Microwave instrument (AMI), which can operate in a Synthetic Aperture Radar (SAR) mode and in a wind-scatterometer mode. It has specific antennas as instrument sensors. The antennas for the SAR and wind-scatterometer have been accurately measured in isolation on the ground before launch. Both SAR and wind-scatterometer instrument have been calibrated in-orbit during the commissioningof ERS-1. Data have been deduced from different sources in order to arrive at information about the antenna behavior. The paper describes these antenna related aspects.
