The patent describes a method of applying a circularly symmetric antenna system to collision avoidance and station keeping with the ability to respond retrodirectively. Specifically, airborne or surface vehicles may employ a method which determines the relative bearing between the vehicles from a single interrogation of one vehicle by the other.
