Abstract

The signal to clutter ration of targets in Synthetic Aperture Radar (SAR) images is a function of the resolution cell and the backscattered radar cross section (RCS) of the target where both the resolution cell and the RCS of the moving target are a function of the time. Due to the long integration time both the SAR look angle and the spatial reflection pattern vary during the integration. Hence, there exist a complex interaction between the spatial reflection pattern, the temporal variation of the moving target, the long integration time and the varying platform look angle. This complex interaction gives an upper and lower limit to the size of simple scatterers such as flat plates. An attempt has been made to try and assess the size and geometry of typical main scatterers of a generic maritime target in order to predict the imaging capabilities of the soon to be launched ENVISAT SAR.
