Abstract
In order to protect the aircraft from attacking surface-to-air missile with precision the algorithm of Activity-through the use of laser thermal imaging system with a receiver matrix type. As a discriminator considered algorithms assess the current position of the energy center of the image and the sum-difference signal processing, carrying out the measurement error angles between the direction of the surface-to-air missile and the optical axis of the matrix photodetector uneven coordinate sensitivity, noise immunity boosting algorithms. Developed a dynamic model of precision tracking, to evaluate the effectiveness of the formation at the entrance of the matrix image sensor in the form of an additive mixture of signal and noise.
