Inverse Synthetic Aperture Radar Imaging Using Fourier Transform Technique

Abstract

Inverse Synthetic Aperture Radar (ISAR) imaging techniques are used to estimate the target spatial image using target backscatter data. In the ISAR measurement environment, the target is often modeled as a collection of point scatterers to take advantage of the Fourier relationship between scatterer location and measured backscatter data. The technique is utilized for imaging a target based on employing scattering mechanism and Fourier Transform (FT). With Processing the backscattered data ISAR image, using the Inverse Fourier Transform (IFT), the target’s range and cross range are formed and imaging is formed accordingly.
