Abstract
Abstract A small boat surface to surface weapon control system comprising search radar, TV camera, laser transmitter and a semi-active guided missile is disclosed. The target is initially located by radar scanning devices and the bearing is transferred to a television camera mechanism which is mounted on the same mast as the radar antenna. The television camera and a laser gun will then be pointed in the direction of the target. A blossom on a television screen which coincides with the image of the target indicates that the laser gun is on line with the target. The missile is fired and rides a reflected laser beam to the target.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
A weapons control system for small boats comprising: search radar apparatus for sighting and ranging potential targets; a telEvision camera responsive to a command signal created in response to sighting of a potential target on said radar to align said camera with the receiving antenna bearing of said radar apparatus; a laser transmitter mounted in proximity to said television camera and responsive to movements of said camera to align itself along the same bearing assumed by said camera; and laser beam detector means mounted in nose of a guidable missile responsive to a target reflected laser beam to cause said missile to ride said beam to said target.
Claim 2
Dependent Claim
108 words
A weapons control system for small boats comprising: search radar apparatus for sighting and ranging potential targets; a telEvision camera responsive to a command signal created in response to sighting of a potential target on said radar to align said camera with the receiving antenna bearing of said radar apparatus; a laser transmitter mounted in proximity to said television camera and responsive to movements of said camera to align itself along the same bearing assumed by said camera; and laser beam detector means mounted in nose of a guidable missile responsive to a target reflected laser beam to cause said missile to ride said beam to said target.
Claim 3
Dependent Claim
48 words
The weapon control system of claim 1 further comprising a television receiver responsive to said television camera to diaplay images of said target and said reflected laser beam, whereby a coincidence between the target image and the reflected laser beam image indicates said laser transmitter is on target.
Claim 4
Dependent Claim
19 words
The weapons control system of claim 2 wherein said laser beam detector means comprises a four quadrant silicon detector.
Claim 5
Independent Claim
126 words
A method for controlling fire power of surface craft utilizing search radar apparatus, a television camera, a laser transmitter rotateably mounted on a mast, a television receiver responsive to said camera, a guidable missile, and a laser beam detector means mounted in nose of said missile, comprising the steps of: detecting a target by means of said search radar apparatus; rotating the television camera to assume bearing of the receiving antenna of said radar apparatus; rotating the laser transmitter to assume the bearing of said television camera; manually adjusting said laser transmitter on target by coinciding target image and reflected laser beam blossom on said television screen; and launching the guidable missile so it will intercept the reflected laser beam and ride it to the target.
Claim 6
Independent Claim
126 words
