Abstract

The use of a hybrid 2-D spectral analysis method in RCS (radar cross section) imaging is presented. The hybrid scheme uses the standard FFT (fast Fourier transform) technique and the super resolution MUSIC algorithm subsequently to form the 2-D image. This approach can have the advantage of improving the resolution in the dimension where short data records are available. This hybrid approach was applied to the 2-D RCS analysis of a cube. The results are given for the case where the RCS data over an aspect angle of 10 degrees are considered. They indicate that by using the hybrid scheme, the scattering centers associated with the target are resolved as expected, whereas the standard 2-D FFT algorithm failed to identify the scattering centers.<>
