Paper Abstract

The primary measurement objective of the Advanced Scatterometer ASCAT, a spaceborne real aperture C band radar, is the determination of wind fields at the ocean surface. Unlike AMI instruments on-board ERS satellites, ASCAT uses long transmit pulses with linear frequency modulation (chirps) allowing the application of low peak transmission power while retaining a high SNR. A pulse-compression is performed on the received signal. This paper will focus on the impact of the use of pulse compression in particular on the location accuracy of the samples in presence of external perturbations. An eventual location error has important consequences on the normalization as well as on the geolocation of the measured data.
