摘要:
This paper provides an analysis, together with simulation, of the accuracy with which the quadratic focus parameter used in generating SAR images can be obtained. Previous analyses expressed the error in this quantity in terms of a depth-of-focus measure. We demonstrate that considerably greater accuracy can be achieved under certain conditions. We derive the predicted error in this parameter for a point target on a weak background and also introduce the effect of extended random targets within the scene.
