Model of motion route of unmanned aerial vehicles operations with obstacles avoidance

Abstract

The aerodynamic model of the group of unmanned aerial vehicles in space with obstacles is investigated in this paper, the model development is based on the methods of Dubins trajectory formation and Pythagorean spatial theorem concerning hodograph. It is determined that one of the classic trajectories used for unmanned aerial vehicle maneuver from one height to another is the intersection of circular spiral projected onto the X-Y plane in the form of a circle. The problem of obstacle avoidance is determined and Dubins diagram for two unmanned aerial vehicles routes in the environment with obstacles is given. On the basis of the specified scheme the algorithm of re-laying the UAV route with curvature adjustment by means of intermediate point which is taken out on the second scheme is described. Analysis of the known solutions in the field of increasing the route stability control for unmanned aerial vehicles and electronic suppression demonstrate the importance of the problem of forming the flight routes of unmanned aerial vehicles by passing opposing enemy areas, taking into account the peculiarities of air defense and electronic warfare application. The functional scheme of UAV recognition mechanism in the conditions of radio attacks is developed and the mechanism of formation of UAV safe movement in the conditions of radio attacks based on three basic techniques is defined.
