Spatial considerations in SAR speckle consideration

An approach to the simulation of synthetic-aperture-radar (SAR) image products is described that departs from most of the other simulation algorithms in the method of speckle generation. Speckle is prepared corresponding to the combination of the frequency weightings and look sum strategy of the radar processes desired and then multiplied by the source scene data preconditioned by the desired resolution. The method allows output pixel spacings to be specified independently of more fundamental system parameters. Typical results are presented for SIR-B images.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
