The Research Of UCAV Combat Simulation Modeling

With the increasing development and widely used of UCAV in recent years, the research operational effectiveness evaluation for UCAV is growing day by day. This paper constructed a UCAV combat simulation modeling and made a calculations and analysis, which based on the study of the UCAV operations process at first. And then, it studied manned and unmanned aircraft to ground to attack the problem in the future, established the effectiveness of the assessment model,in which the details are as follows:According to the characteristics of UCAV, the attack pattern and progress was analyzed, that is the timeliness goal and un-timeliness goal; according to the previous operation case and future combat environment, it set the typical engagement profile of attack type UCAV. Among them, there are the high-high-high, high-low-high, low-low-low., three kinds of typical engagement profiles.In order to more in-depth study under the field air defense conditions of the UCAV characteristics, The paper was set up a combat simulation model of attack type UCAV with object oriented method. This part of the contents of the study include: the field air defense combat environment scenario, the attack and defense simulation process and the main ground attack stage model. Through the analysis of ground attack model, it built ground attack UAV simulation system.The system can simulate the whole process of attack UAV ground attack and thus made an assessment of the effectiveness of ground attack.On the basis of the simulation model can be effectively used for ground attack UCAV effectiveness evaluation. Through different simulation results of different parameters under the same conditions, it can get that result: Airborne auxiliary defense system of UCAV itself is more than RCS can improve the UCAV penetration probability;synthetic aperture radar can enhance the detection ability of drones more than optical equipment identification, storage capacity is more can improve the UCAV recognition ability; air to surface missile is higher than the precision guided bomb damage ability. In general can be learned, UCAV need better battlefield perception capability,more intelligent, more powerful ability of the attack ability, these are for the UCAV omnidirectional radar warning system, defense system, identification system, the airborne radar system, airborne weapon system put forward higher requirements.The cooperation of manned/unmanned fighters for air-to-ground attack will be the main mode in the future combat, how to evaluate the operation effectiveness is an important subject need to solve. First of all, according to the four phases of the task, the chief probability model isestablished; Then based on bridging model, the probability model of each part is established;Finally, through calculation example that a manned fighter co-operates with two UCAV`s to attack ground target, analyzed problems about the comparison between cooperation and noncooperation,the usability and applicability of the model is verified.
