ADAPTIVE INFRARED OPTIMIZATION ISSUES THE GUIDING HEAD OF ROTATING PROJECTILES

In order to stabilize the flight path of guided projectiles, the rotational motion of the projectiles is often used. The rotation of the projectile creates significant difficulties for the projectile’s scanning system, which aims at the target. To solve this problem, the space scanning method is used by installing a line of photosensitive devices in the radial direction on the imaging plane of the scanning system of the guidance head of a rotating projectile. Two optimization problems for implementing adaptive control of the focal length of projectile optics are formulated and solved: (a) control of the focal length, depending on the distance to the object; (b) control of the focal length, depending on the width of the detector in the far sector of the trajectory departure detection disk. It is determined that in the first case, a direct relationship between the function and the argument of the adaptive equation is required, and in the second case, an inverse relationship.
