Hi Steve,
Indeed..
It was one of many night time thoughts, this is the plan.
There is going to be a camera on top of the boat either where the long range radar unit is located (360 deg rotation) or in the range finder above the bridge, this is going to do a few things.. Provide a view which will be displayed on the controller screen, use a parallel laser beam to determine range (the radar) and for guidance of ordinance... the gun and other things not yet covered, I have a laser output on the board of the gun which is switched on when a target is selected it will move to the same azimuth position always pointing down the barrel (considering the distance apart from the camera) then the fine tuning will be that the laser dot seen by the camera will be moved to the center of the screen (where I am aiming)...
The other method which will also be possible is that you could use a laser pointer which is pulsed with an encoded sequence (like Morse) which the camera will be looking for on it's radar rotations, once it finds it depending on which (Morse) code it is it will assign the gun and fire that many shots or release something else which I haven't covered yet.
As range is known and power/elevation is fully controlled, hitting the target every time shouldn't be a problem.
