Abstract :
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 in the AOA estimator.
