A system for enabling homing by a missile onto a target which is marked by a beacon at some other location. A radio frequency beacon is located remotely from the intended target. Target coordinates relative to the beacon are obtained and relayed by conventional means to the launch site and are stored in missile memory. During flight the missile seeker acquires, interrogates and tracks the beacon. The missile borne equipment generates guidance signals which alter the trajectory to the target location.

A system for enabling homing of a missile onto a target, said target having a radio frequency beacon disposed at a remote predetermined distance and direction therefrom: a missile having computer means thereon for storing signals indicative of the distance and direction of said target relative to said beacon for storing signals indicative of the inverse of the coordinates of said target; seeker means carried by said missile for acquiring and tracking beacon radiations, said seeker means disposed for emitting signals indicative of spatial coordinates thereof responsive to acquiring and tracking said beacon radiations; said computer means disposed for comparing said signals indicative of said seeker coordinates with said inverse target coordinates and providing signals indicative of the differences in said coordinates; and, means carried on said missile for receiving said signals indicative of the differences in and coordinates for guiding said missile in a direction to reduce to zero the differences between the target coordinates and said inverse coordinates responsive to beacon emissions to home the missile onto the target. A method of homing a missile, having a guidance computer thereon and a seeker responsive to a predetermined signal frequency, onto a target comprising the steps of: placing a beacon remote from a target; surveying the target area relative to the beacon to determine the geographic coordinates of said target area, said geographic coordinates being defined as azimuth, range and elevation; providing signals to said guidance computer which signals are correlative with said geographic coordinates; surveying said target area to determine the beacon\s distance and direction from said target and providing signals to said guidance computer which are correlative with the beacon\s distance and direction from said target; establishing control communication between said beacon and said missile whereby said beacon responds to the missile seeker frequency thereby enabling the seeker to locate and track the beacon; and, receiving and comparing signals of the seeker coordinates with the inverse of the signals of the target coordinates stored in the computer memory until the missile is at the target.
