The calibration of the ERS-1 synthetic aperture radar using UK-PAF imagery
Abstract
Calibration of the ERS-1 synthetic aperture radar has shown that users are required to make corrections for replica pulse power variations and for the non-linear response of the on-board analogue to digital convertor (ADC). The replica pulse variations can be as much as 1.8 dB while the ADC can lead to underestimates of up to 3.3 dB in radar cross-sections measurements. The precision of the corrections is estimated to be better than 0.5 dB. A full expression to enable distributed and point target radar cross-sections to be calculated is given.
