摘要:

为适应军事发展的要求,基于经典火控系统结构,首先设计了火控仿真系统的系统框架,建立了仿真系统的各子系统数学模型；而后基于嵌入式VxWorks实时操作系统,实现了各子系统功能模块及其间的通信；最后,基于所实现的火控仿真系统,在不同国产武器配置类型下,实现了空空攻击想定条件下的两组实例仿真研究. 仿真结果表明：空空攻击时,若进行近距离格斗,选择霹雳-8(PL-8)较好,若是远距离格斗,则选择霹雳-12 (PL-12)更适宜,更能保证攻击路线的稳定性和平滑性.

Abstract:

To meet the requirements of military development, firstly, the framework of the fire control simulation system (FCSS) is designed; then establishes every mathematical model of the fire control system, including the test management subsystem model, the weapon management subsystem model, the flight control subsystem model, the sensor management subsystem model and the fire control task machine subsystem model; secondly, based on the embedded real-time operating system VxWorks, this paper realizes the functional modules of each subsystem, and on this basis realizes the communication among them; finally, two sets of simulation results are analyzed in air-attack. Simulation results show that: to ensure the stability and smoothness of the attack route, PL-8 is better in the air to air missile fire control attack, PL-12 is more suitable in the long-distance combat.
