Counter countermeasure method for missile's imaging infrared seeker

Popis výsledku v původním jazyce

This paper deals with an elimination of jamming optoelectronic seekers by flares. It is predominantly focused on the design and testing of the method of object discrimination for imaging infrared seeker. To design this method, an analysis of capability of imaging infrared seekers to discriminate objects according to their shape was used. On the basis of the results of this analysis, the principle of object selection by their motion inside the field of view of the coordinator was selected for the design of the method of object discrimination. To test this method, a computer program based on input conditions was created to compute trajectories of aircraft and flares. A further computer program simulating the behavior of the imaging infrared seeker and the missile itself uses information about the trajectory of aircraft and the flares to estimate relative position of those objects and the missile. It also evaluates the position of the entire object within the field of view and chooses a proper object by using the designed method of object discrimination. As an indicator of the success rate of the designed method to properly choose a good target (aircraft), the miss distance was used. On the basis of the achieved miss distances for various initiate relative positions of the missile and the aircraft and for various sequences of the flare dispense with aircraft maneuvers, the decision-making criterion is defined whether the method was successful or not. The evaluation of the success or failure of the method is realized by percentage of failure simulations from all realized ones under given input conditions.
