Guided missile systems have evolved at a tremendous rate in the last four decades, and recent advances in technology ensure that intelligent warheads will play an increasingly important role in maintaining our military superiority. For ethical reasons, one prays that each warhead deployed during an exit will only attack its target, and that innocent civilians will not be harmed by a power failure. From a tactical point of view, our army wants a weapon that is reliable and effective, inflicting maximum damage on valid military objectives and guaranteeing our ability for rapid attacks with precise accuracy. Guided missile systems help meet all these demands.
The laser guide is used by the military to guide a missile or other projectile or vehicle to a target by means of a laser beam (Lidar), eg. Semi-active beam or radar guide (SARH). This technique is sometimes called SALH, for Semi-Active Homing Laser. With this technique, a laser remains pointy on the target and the laser radiation bounces off the target and disperses in all directions (this is known as "paint the lens" or "laser paint"). The missile, the bomb, etc. Is thrown or falls somewhere near the target. When it is close enough for a part of the laser energy reflected from the target to reach it, a laser finder detects which direction this energy comes from and adjusts the projectile's path to the source. While the projectile is in the general area and the laser remains directed at the target, the projectile must be accurately guided to the target. However, SALH is not useful against targets that do not reflect much laser energy, including those coated with special paint that absorbs laser energy. This is likely to be widely used by advanced military vehicles in order to make it harder to use laser designators against them and harder to hit with laser guided ammunition. An obvious circumvention would be simply to aim the laser closer to the target. Countermeasures to laser guide are laser detection systems, smoke screen, active anti-laser protection systems.
