Abstract :
The impulse responses of a target for a limited bandwidth (at several aspect angles) are used to generate the ISAR (inverse synthetic aperture radar) image of the target. The high-resolution images for a test target are then compared to the FT (Fourier transform)-based ISAR images. For a 2-GHz bandwidth, the FT-based image and the image obtained from high-resolution PSD are shown. For this bandwidth it can be seen that the image generated from the high-resolution PSD more clearly resolves the individual components.<>
