Synthetic aperture radar imaging provides high resolution
images of large areas. The intensities of pixels in a SAR
image are based on the spatial orientation, roughness, and
dielectric constant of the surface imaged.
SAR is an active sensor, transmitting its own energy, and
then measuring the return scattered by the earth抯 surface
back to the satellite抯 antenna. SAR processing is the
transformation of raw SAR signal data into a spatial image.
In this communication, we present a contribution
concerning implementation of a SAR image formation with
the IDL language. This process is performed in a frequency
domain correlation of the received signal including range
compression, range migration, and azimuth compression.
The output is the final step in which the data is transposed
back into its original format and written to an output file.
