“…One of the most important components of an anti-aircraft self-guiding infrared missile is the optoelectronic self-guiding seeker. This type of device is still the subject of intensive research in many scientific centers around the world [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. The issue of this article refers to the publications [16,17] and is a continuation of the research conducted on the designed optoelectronic scanning and tracing seeker, presented in Figure 1.…”

The paper presents the concept of controlling the designed optoelectronic scanning and tracking seeker. The above device is intended for the so-called passive guidance of short-range anti-aircraft missiles to various types of air maneuvering targets. In the presented control method, the modified linear-quadratic regulator (LQR) and the estimation of input signals using the extended Kalman filter (EKF) were used. The LQR regulation utilizes linearization of the mathematical model of the above-mentioned seeker by means of the so-called Jacobians. What is more, in order to improve the stability of the seeker control, vector selection of signals received by the optoelectronic system was used, which also utilized EKF. The results of the research are presented in a graphical form. Numerical simulations were carried out on the basis of the author’s own program developed in the programming language C++.
