The SAR/scatterometer study (SAR in 2D-2FS operation)
Abstract
Ocean scatterometer and SAR equipment commonality on ERS-1 was examined. Reduction of mean power and the effects of reduction on the system, and data handling prior to recording and transmission to the ground were studied. Mean power can best be reduced by reducing pulse length while maintaining bandwidth. The short pulse lengths of the SAR and wave scatterometer are compatible with the SAR klystron. A separate TWT is proposed for the wind scatterometer. Since this is a long pulse transmitter, the klystron is regunned in order to enable it to operate in a long pulse mode if the TWT fails. Data processing software and hardware choice depends on the amount of auxiliary data required and synchronizing problems associated with each system in the final configuration.
