Abstract

This paper concentrates on the focusing for hybrid bistatic SAR configurations, consisting of a space borne/airborne carrier configuration with considerable differences in velocities and altitudes of transmitter and receiver. Therefore the direct implementation of a bistatic SAR focusing algorithm based on Loffeld´s bistatic formulae (LBF) cannot be readily applied. An extension of the bistatic point target reference spectrum, based on LBF is derived. Simulated focusing results verify the proposed approach.
