Abstract

A system comprises a RF antenna connected to a vehicle, a primary radio altimeter connected to the antenna, a secondary radio altimeter comprising a millimeter wave radar sensor, and a processor coupled to the primary and secondary radio altimeters. The processor determines whether an altitude detected by the primary radio altimeter is greater than a threshold altitude. If the altitude is greater than the threshold altitude, the altitude detected is used and signals from the secondary radio altimeter are discarded. If the altitude is not greater than the threshold altitude, the processor identifies whether signal interference from a cellular network source is present based on any abnormal signals from the primary radio altimeter. If abnormal signals are not present, altitude estimates detected by the primary and secondary radio altimeters are correlated. If abnormal signals are present, signals from the secondary radio altimeter are processed to detect a vehicle altitude.
