Abstract :
The Aquarius mission requirement for 0.1 dB scatterometer measurement stability has driven the radar´s control and processing hardware design. Two new aspects of the flight electronics that contribute toward the overall stability will be discussed in this paper: 1) a high- rate radar timing mode for verifying performance on the ground, and 2) an onboard processor for flagging echoes corrupted by radio-frequency interference (RFI).
