英文摘要	A full-wave electromagnetic simulation of inverse synthetic aperture radar (ISAR) using two-dimension (2-D) finite difference time domain method (FDTD) is presented with multiple signal classification (MUSIC) method used to investigate the scattering center in radar image. Full-wave electromagnetic simulation can account for multiple scattering effect usually exists in real case, but ignored when ideal point-targets are treated as scattering centers, so it can help us understand the scattering mechanism of complex target. Fourier-based imaging algorithms are fast and robust, but they are limited in resolution and dynamic range. Subspace eigen-value analysis based methods, such as MUSIC, is able to provide superresolution and accurately recover the scattering center locations even for a small number of correlated samples. Simulations show that with techniques of full-wave electromagnetic calculation and superresolution, one can get an insight into the relation between multiple scattering effects and scattering centers formed in ISAR imagary.
