Abstract :
This paper presents the algorithm to synthesize apertures using reflected GPS signal. In this concept, while GPS satellite is utilized as non-cooperative transmitter, receiving platform flies much closer to the Earth´s surface and therefore there is an asymmetry in the geometry. Hence we refer to this geometry as quasi mono-static and by considering this asymmetry as well as the characteristics of GPS signal, we established the algorithm to reconstruct the PSF from the reflected GPS signal. We also conducted a hardware simulation by using GPS signal generator and confirmed the validity of our proposed theory.
