SAR, image formation, range Doppler algorithm.
Range Doppler Algorithm (RDA) is the first algorithm
that has been used to reconstruct the synthetic aperture
radar (SAR) image formation. The data can be gathered
from both airplane and satellite. Data gathering by
satellite is general. The problem with space born data
gathering is range cell migration which is generated by
the relative motion between satellite and terrain being
imaged during data gathering. In this paper we implement
the range Doppler algorithm on space born real data
gathered from RADARSAT to generate SAR image and
compensate the effect of range cell migration.
