Abstract : The study is a comparison of three methods for determing the azimuthal direction of arrival by processing the output from a scanner used with a CDAA. The three methods use the sum amplitude, difference amplitude and differential phase patterns, respectively, as the basis for determining directions of arrival; each of the methods employs a digital computer to perform the necessary computations.
