SYSTEM AND METHODS FOR GUIDING MUNITIONS

摘要

A method of guiding a munition (20) to a target (10) transmitting one or more signals is described. The method includes configuring the munition with a radio frequency receiver (60), an antenna (62) for the receiver mounted such that a main beam of the antenna pattern (40) for the antenna is offset from a line of flight axis (42) of the munition by an angle (26) and configuring the munition to rotate along an axis substantially similar to the line of flight axis of the munition. The method also includes configuring the munition to process signals received at the antenna, wherein heading changes of the munition, the angle of the main beam of the antenna from the line of flight axis, and the rotation of the munition result in the received signals having amplitude variations. Directional corrections are: generated for the munition to direct the munition towards the target based on amplitude variations in the received signals.
