that is like a very basic but useful application of machine learningThe fire control systems on the Type 022 would have to be upgraded for this, just as they would need to on the 056 and 054A. To operate, a digital image of the target ship would have to be downloaded from a database in the ship's computer to the missile’s guidance computer. This YJ-83 doesn't work on the thermal homing principle as the YJ-83 with the dimple for a thermal homing seeker. The imaging infrared takes the image of the target ship and compares it to the one that's uploaded from the database and stored in the missile's computer. If the image is a match, the missile then homes in on the target. This kind of homing system is much more difficult to fool or decoy with flares.
