For focusing airborne parallel translational variant SAR, an analytical imaging algorithm based on the extended Loffeld bistatic formula (ELBF) is proposed. With the bistatic geometry, point target (PT) position offsets to the transmitter track are expressed in terms of PT position offsets to the receiver track. Then phase terms of spectrum are divided into range and azimuth phase terms. The bistatic deformation (BD) term is compensated in 2-D frequency domain, and space variances of range and azimuth phase terms are eliminated by chirp scaling (CS) method and chirp z-transform (CZT) respectively. The proposed imaging algorithm is verified by simulations.
