The Algorithm of Trajectory Control of an Unmanned Aerial Vehicle and Its Radar Antenna when Forming a Radar Image a Land-Based Facility

In the article, based on the mathematical apparatus of the statistical theory of optimal control, the optimal method and algorithm for trajectory control of an unmanned aerial vehicle carrier of a small airborne radar station in the formation of radar images – video frames of ground objects is synthesized. The accuracy of the formation of high-resolution radar video frames obtained by radar synthesis of the antenna aperture depends on the trajectory instabilities that occur during the flight of an unmanned aerial vehicle. This determines the need to develop algorithms for trajectory control of carriers of small-sized airborne radar stations and their antennas, taking into account the peculiarities of video frame formation over the time interval of antenna aperture synthesis. The formation of the required flight path with the antenna orientation based on the algorithm developed in the article will make it possible to ensure more efficient operation of small-sized airborne radar stations placed on unmanned aerial vehicles during the flight mission.
