Abstract :
This paper concerns the simulation of inverse synthetic aperture radar (ISAR) image for radar targets based on the shooting and bouncing ray (SBR) method. Contrary to the conventional approach where the ISAR image is obtained by inverse Fourier transforming to the scattering field, we adopt a newly-developed method [8], where the Fourier transformation has been merged into the SBR algorithm. Such a method has been improved and used in the imaging of real-size aircraft. High resolution two-dimensional ISAR images have been obtained. Hence such a method is considered as a general tool for the characterization of large and complex targets.
