The paper presents the kinematics of mutual movement of an unmanned aerial vehicle (UAV) and a ground target. The controlled observation and tracking head (OTH) is a device responsible for observing the ground, searching for a ground target, and tracking it. The preprogrammed movement of the UAV on the circle with the simultaneous movement of the head axis on Archimedes’ spiral during searching for a ground target, both fixed (bunkers, rocket missiles launching positions, etc.) and movable (tanks, infantry fighting vehicles, etc.), is considered. Dynamics of OTH during the performance of the above mentioned activities is examined. Some research results are presented in a graphical form.

Abstract. The analysis focuses on the dynamics of a hypothetical anti-aircraft system during the missile launch. The results of the computer simulation of motion of the launcher-missile system are represented graphically. The diagrams provide information about the range of kinematic excitations acting on the opto-electro-mechanical coordinator of the target in a self-guided missile.

Today's self-propelled anti-aircraft missile systems are designed to intercept low-flying, manoeuvring targets not only under any weather conditions but also during movement of the carrier vehicle over rough terrain. As target search and tracking need to be reliable, i.e. not affected by unfavorable conditions, a self-propelled surface-to-air missile system requires suitable stabilization and control systems. This implies that it is necessary to develop an adequate mathematical model of the missile system dynamics. In this article, we propose a procedure for experimental design to determine the coefficients of such a model. Particular attention is paid to the algorithm for selecting optimal controls and a timedependent measurement spectrum to minimize the assumed criterion of quality.
