Experimental Verification of the Performance of the Aperture Sampling Technique

Abstract

An experimental verification of the aperture sampling technique as a means of estimating the angle-of-arrival in the presence of ground reflection interference is reported. The technique is found to perform satisfactorily down to 1/5 of a beamwidth elevation. Beam splitting better than 20:1 is demonstrated. This performance is obtained by using a minimizing search processing that allows use of a larger number of samples than the number required by the closed form solution.
