Research On Air-to-air And Air-to-ground Super-maneuver Attack Of UACVs Based On Tactical Digital Information Link

This thesis mainly works on TADIL (the abbreviation of tactical digital information link), multi-fighter coordinated multi-target attack, super-maneuver attack and air-to-ground attack. It is supported by the Tenth Five-Year Advanced Research Foundation of China Air Force.First of all, we bring forward the basic project of TADIL, which adapts to combined operations. It is suggested to use TDMA (the abbreviation of time division multiple access) as the working pattern and utilize the concept of Mobile Ad Hoc Network to construct the data link network. Aiming at the impact of time delay on data link and the characteristic of cooperative combat under the command of director aircraft, this thesis applies a kind of Kalman filtering algorithm in polar coordinates to compensate the error of time delay, and then does the transformation of target motion parameters to obtain the current information of target. The result of simulation indicates validity of this method.Secondly, we study combat decision algorithm based on data link in three dimensional space and consider a new decision model to do the more effective situation evaluation. We apply TOPSIS to decision of single-to-multiple attack successfully and complete the simulation. Then we solve maneuver decision problem by matrix games. Also, we discuss the grouping scheme and multi-fighter coordinated decision-making in each small group. According to the study above, we bring forward combined RBF-RBF neural network to target assignment and attack sequence decision, which is proved to be feasible by Matlab simulation.Thirdly, we build mathematics model of super-maneuver fighter and part the aircraft states to two loops based on principle of time delay. Then nonlinear dynamic inverse theory is applied to design the flight control law. At the same time, we simulate Herbest maneuver by this flight control system.Fourthly, we discuss and simulate the transformation method of relative parameters of ground target based on data link. And then we analyze decision algorithm of air-to-ground attack. Especially, we educe three dimensional terminal guidance law of air-to-ground missile in the disturbance of wind, and give the simulation result.Finally, we develop 3D animation simulation software, which vividly demonstrates the process when air-to-ground missile is attacking certain ground target.
