Efficient ω-k-algorithm for circular SAR and cylindrical reconstruction areas
Technische Universität München, Lehrstuhl für Hochfrequenztechnik, Fachgebiet Hochfrequente Felder und Schaltungen, D-80333 München, Germany
Abstract. We present a novel reconstruction algorithm of ω-k type which suits for wideband circular synthetic aperture data taken in stripmap mode. The proposed algorithm allows to reconstruct an image on a cylindrical surface. The range trajectory is approximated by Taylor Series expansion using only the quadratic terms which limits the angular reconstruction range (cross range). In our case this is not a restriction for the application. Wider areas with respect to cross range can be realized by joining several reconstructed images side by side to build a wider image by means of digital spotlighting.
