载舰环境仿真方法研究

Research of Simulation in Ship-borne Environment

文章简要分析了对载舰环境的仿真需求,并重点介绍了目标仿真、载舰姿态仿真和时统设备仿真方法。针对舰载雷达,主要分析了影响搜索视距的因素和对不同雷达截面积目标探测能力。针对载舰姿态,着重分析了载舰横摇和纵摇仿真方法[1～3]。针对时统,着重分析了利用GPS和BD进行授时的方法。载舰环境仿真是仿真试验的关键环节,一方面可以为仿真试验提供不同条件下的载舰环境,完成仿真试验,另一方面也可以为实装提供不同条件下的载舰环境激励,实现虚实合成试验。这就使得许多难以实施或不能实施的试验成为可能,最终对武器系统性能作出客观的评定。

The paper analyses the need of simulation for ship-borne system,focuses on the introduction of the way of simulation in target、attitude of ship and time system.As for ship-borne radar,it analyzes the factors of searching capacity and detect ability in different sectional areas.As for the attitude of ship,it analyzes the way of simulation in rolling and pitching.And for time system,it focuses on the way of GPS and BD.Simulation in ship-borne environment is the key of simulation test,it can not only provide different ship-borne environment which tests need,but also provide different encourages that the tests need.It makes some test which is hard to make in real world become true,and evaluates the performance of weapon system objectively.
