ISAR Imaging Using Fourier and Wavelet Transforms

Abstract

We investigate the ISAR imaging model using two different approaches the Fourier and the wavelet transform. Starting from the weak-scatter far-field model we explain why this approximation it's a Fourier Transform. We investigate the scattering mechanisms from different surfaces. We also analyze and derived the expressions of the scatter from sphere. We briefly discuss the radon transform and why it's not a good approach to our problem. We investigate the results using this time-frequency methods, creating images using synthetic data.
