Abstract

In this paper the efficient kernel evaluation technique is extended and used to analyze the impact of space variance of the SAR acquisition geometry on ROSE-L SAR images, in particular when Fourier-based focusing kernels are used. The idea of the efficient kernel evaluation technique is to perform a numerical calculation of the focusing performance for a given mission with the corresponding orbit and system parameters. This assessment can be performed for several geographical locations in order to obtain the global performance of the focusing kernel. Based on the obtained results and considering the system requirements, it shall be decided whether the space variance needs to be accommodated with additional processing steps. The use of such a tool allows for the design of the focusing kernel prior to the actual implementation and validation with time-domain simulations of point targets.
