Abstract : Eight cases of CDAA direction-of-arrival data having large standard deviations are studied in detail to determine the source of the deviation error. It is shown that the wave interference conditions between two, or more, dominant plane waves arriving from different azimuthal angles of arrival or different elevation angles of arrival can account for the observed effects. Various testing criteria for accepting or rejecting the data are proposed. (Author)
