Abstract


So-called helicopter the smart fire control system, artificial intelligence technology and helicopter gunship fire control system combining the use of artificial intelligence the airborne weapons fire command and control problems of intelligent design, and neural networks, fuzzy control, genetic algorithms, etc. basic, to deal with the worsening Modern helicopter combat uncertainty and complexity. Design based the intelligent data chain helicopter fire control system, mainly around four part expansion: that the the helicopter missile three-dimensional smart guide law, between the helicopter data link system, helicopter air combat decision-making systems, 3D Intelligent Guidance Law missile attack simulation study. First, the reference to the third generation of short-wave communication technology systems MTL-STD-188-141B, analysis of the factors affecting the effect of data link communications, and then design datalink between a helicopter view of these factors, and the Kalman filter algorithm process the data link transmission delay compensation, with a large number of digital simulation to verify the effectiveness of the algorithm. Second, the research-based the data chain helicopter air combat system of collaborative decision making: First, given a the helicopter combat situation analysis method; then on the basis of the trend analysis method, given the traditional helicopter air combat threat evaluation and formation method and with genetic algorithm to Air Combat Decision optimization; Then, Firepower allocation method based on ant colony algorithm; final decision Helicopter Combat Maneuvering both the analysis of the traditional fleet tactical maneuver, based on a kinds of fuzzy neural network-based compensation helicopter maneuvering decision-making method. All of the above methods are a large number of digital simulation results also proved the correctness and validity of the above methods. In the next chapter using a variety of data indicators to analyze the advantages and disadvantages of the Missile Guidance Laws for, then a genetic annealing algorithm based on variable universe 3D fuzzy guidance law, at the same time gives a RBF network missile three-dimensional method of the attack zone, and compared both performance through digital simulation. Multigen-Paradigm creator and Vega simulation of three-dimensional animation in the VC environment is described in the last part of our helicopter found the target, to determine whether the target and make a decision to launch air combat missile target three-dimensional animation and The three-dimensional animation vividly demonstrates the entire process of the missile attacks on targets, and vivid visual validate the correctness of the guidance law.
