Ground Target Detection in Forward Scattering Radar Using Hilbert Transform and Wavelet Techniques

This thesis analyzed the electromagnetic signal scattered from the target crossing the Forward Scattering Radar system baseline. The aim of the analysis was to extract the Doppler signal of the target, under the influence of high ground clutter and noise interference. The scattered Doppler signal wa...
