A system for locking a missile seeker to a desired target signal while the issile is in flight and approaching the target. The target is detected and tracked by a remote radar. The missile is launched and utilizes an inertial mid-course guidance to guide it in the general direction of the target. A data link is established between the remote radar and the missle seeker. When the missile is sufficiently close to the target its active radar is turned on and target information is transmitted via the data link to the remote radar or tracking station. The remote tracking station transmits back to the missile information for correcting its tracking course and provides information which effects missile seeker lock-on of the target of interest and will cause the missile seeker to continue to track the target until impact.

DETAILED DESCRIPTION What is claimed is: 1.
In a remote target system for guided missiles, the combination comprising: (a) a radar located at a remote station for detecting and tracking a target, (b) a self-propelled guided missile launched from said remote station on a course established by said tracking radar, (c) said guided missile having seeker means for detecting and tracking said target, (d) a guidance data transfer unit coupled to said missile seeker for transferring guidance data between said missile seeker and said tracking radar, (e) said missile seeker being responsive to guidance information received from said tracking radar for acquiring and locking-on said target in a homing mode, (f) said guidance data transfer unit including a control switching unit for transferring guidance information supplied for the guidance of said missile from the pre-established course to guidance information supplied by said missile seeker in response to a command signal from said tracking radar.
2.
The system of claim 1 wherein said tracking radar is a pulsed search radar.
3.
The system of claim 2 wherein target tracking information is automatically transmitted to said missile by phase modulation of the pulse repetition frequency of said tracking radar.
4.
The system of claim 3 wherein said guidance data transfer unit has means for decoding said phase modulated information signals.
5.
The system of claim 4 wherein said guidance data transfer unit includes means for transmitting the corrected guidance data to the radar to form a data transfer closed loop.

Description:
BACKGROUND OF THE INVENTION The present invention relates to remote targeting systems for guided missiles and more particularly to remote targeting systems for guided missiles wherein a means is provided for the missile seeker to lock-on a desired target signal while the missile is in flight and approaching the target.
This situation occurs especially in tactical situations where long stand off by the launch aircraft is advisable
