Abstract
Methods, apparatuses, and systems for verifying alignment of a compact antenna test range (CATR) are presented. A radio frequency (RF) profile may be generated based on test signals received by a reference antenna at a plurality of orientations. Phase and amplitude data of the RF profile may be used to determine whether the CATR is aligned properly.
