Abstract
The aim of this paper is to study the effect of speckle on wide frequency components in synthetic aperture radar (SAR) images. In this study, the presence of speckle in SAR images is analysed using frequency domain techniques. SAR images consists of many features such as lines, edges, point targets, structural boundaries, homogeneous areas. In frequency domain analysis we observe these features occupy wide band of frequency spectra. In formulating the effective speckle reduction techniques, exact knowledge of noise like phenomenon on wide band of frequency spectra in SAR images is necessary. Qualitative and quantitative analysis using fourier transform helps to conclude this study.
