The Thomson method of multiple-windows is applied to the problem of angle-of-arrival (AOA) estimation at low grazing angles, and in the presence of combined specular and diffuse multipath. Experimental data are used, collected by means of a 32 element sampled aperture antenna system operating at X-band. Additional improvement is observed when multiple frequencies and a priori information is incorporated...
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.<<ETX>>
