Abstract
The present invention provides an apparatus, method, and computer-executable program for detecting antenna failures in directional antennas. In particular, the present invention compares a bearing calculated from received positional data concerning a target to the bearing of the target determined using the directional antenna. If the calculated bearing and the determined bearing differ by greater than a predetermined amount, it is determined that there is an antenna failure. In this way, bearing information determined by the directional antenna is compared against a piece of known data in order to determine if the antenna is functioning properly.
