Spaceborne-airborne bistatic SAR 3-D imaging using linear array antenna

This paper presents a new concept of Space-Airborne Bi-Static Linear Array SAR (SA-BiLASAR) imaging using array antenna, which inherited the advantages of conventional linear array antenna 3-D SAR and Bi-Static SAR. Firstly, the geometrical model and the signal model are established. Secondly, a time domain back projection imaging algorithm is presented for SA-BiLASAR data processing. In the end, the feasibility of the SA-BiLASAR and the imaging algorithm are demonstrated by simulated results.
