you would think the navy, dealing with missiles being launched, which are bright, and guns being fired, and plane afterburners, in all times of day and all weather would know how to deal with and identify camera aberrations, its dangerous because you might think there is a enemy missile and trigger a defense system.. for some reason I don't think its so simple/foolish.. these military systems must be designed to reduce that and the operators trained on how to identify that. and they float on water all the time and constantly scan everything around them, including odd ball dangers like glint from submarine periscopes (reportedly this was one of the best ways to spot a submarine back in the day), possibly frogman goggles, sub surface ships, etc.. they all rely on identifying glint properly.
or enemy gun fire from a ship or an explosion from a ship (be it under attack or malfunction), after 1000+ years of navy service, would probobly make this.. easy to determine? it did not really change importance over the century, they used to light small fires on boats filled with gun powder to act as torpedos.. the camera is new but I figure they must be EXPERTS at dealing with that and all sorts of optical illusions.
The military was fooled before by stuff like this with early warning systems on satellites, but that was 50 years ago, with lessons learned I am sure.
Microwave effecting pixels maybe? but those thermals are usually shielded with germanium that is conductive I think, and the systems must be RF hardened anyway (so you don't mess up a night vision tube with the radar), so they probobly have all the bells and whistles.
