Abstract
A monitor determines, from the ground, the orientation (roll and attitude) f a missile by observation of the character of a transmitted signal(s) therefrom. By transmitting to a ground receiver a linearly polarized signal(s), the missile identifies a given plane fixed with respect to its body frame. This plane is identified at the ground receiver by comparing the ratio of the signal(s) received in any two cross-polarized directions. To resolve the attendant 180.degree. ambiguity, the monitor employs an antenna array disposed on the missile that is switchable, back and forth, between two equal power lobes. The monitor operates with a single transmitter, and the simple lobe structure of the transmitted signal(s) is obtained using a linearly polarized antenna array with electronic phase switching between the aforementioned equal power lobes.
