5.2. Tlie sirnulated SAR signal ale generated thr.ough a two-clir¡ensional
convolution fol each nodel as desclibecl by Wu ef al. 1112]1. The cligital
sinrulatiorr fol the airl¡olne SAR systern is canied out rvith a 7024 x 7024
irrput data allay, rvhich covers about 4 krn i¡ slant range ancl 400 m 1t azirnuth.
Generally the lalgel azimuth length is includecl in the siraulation, the
more extencled frequency spectra in the /-& domain ale obtainecl (Won and
Moon [108]). A sirnulated SAR siglal aftel the rârìge corrpression is shorvn
