Abstract. Modern wideband radar systems have improved performances for obtaining inverse synthetic aperture radar images of radiating objects. This technics allows obtaining local scattering characteristics in anechoic chambers and radar test facilities. Typically, an image is reconstructed using two-dimensional Fourier transform with first reformatting radar data into rectangular grid in k-space. We propose a method of inverse synthesis with a high dynamic range, based on tomographic processing of back projections. One-dimensional windowing during the image reconstruction process should be applied to reduce the energy of the side lobes. The results of modeling the scattering signal of a metal sphere are proposed.

Key words: radar cross section, inverse synthetic aperture, radar images, tomography, inverse radon transform.
