Since the introduction of a fast Fourier transform (FFT)-based convolution scheme between an impulse train and a ray spread function for the inverse synthetic aperture radar (ISAR) image formation using shooting and bouncing ray (SBR), remarkable progress has been made in reducing calculation time. However, because of an interpolation algorithm, which is(More)
We present a fast 3-D scattering center extraction algorithm using the shooting and bouncing ray technique. The proposed algorithm generates a 3-D inverse synthetic aperture radar image from which a set of 3-D scattering centers is then extracted using the CLEAN algorithm. In the conventional extraction algorithm, computation time is improved using the fast(More)
