Experimental characterisation of diffuse multipath at 10.2 GHz using method of multiple windows

Thomson´s multiple window method of spectrum estimation is applied to the problem of diffuse multipath characterisation in a low angle tracking radar environment. The method gives optimum power spectrum estimates in both the frequency and wavenumber domains. The results presented are based on data collected by means of a 32-element sampled aperture antenna system operating at 10.2 GHz.
