Abstract
The feasibility of utilizing bistatic scattered field data to obtain the microwave ISAR image of a target is investigated. The principle and results of the bistatic imaging algorithm are presented. It is shown that the ISAR image can be reconstructed by Fourier inversion of the bistatic scattered field data under the physical optics approximation. Bistatic scattered field data is faster to simulate using the shooting and bouncing ray technique than monostatic scattered field data hence the bistatic scheme results in time savings. Monostatic and bistatic ISAR images are presented for different targets. The tradeoff between time savings and image fidelity for the two schemes is discussed.
