摘要：

在时间驱动军事仿真中，时间步长设置是平衡运行效率和仿真精度的一个关键技术。基于军事仿真中时间步长设置的研究现状，针对最小时间步长给军事仿真带来的性能瓶颈，设计了轨迹时空交会计算模型，解除了高速目标探测、干扰等交互对最小时间步长的约束。设计了探测交互场景实验，验证了模型在不漏交互、仿真效率提升方面的有效性。

Abstract:

In time-driven military simulation, time-step setting is a key technology for balancing operational efficiency and simulation accuracy. Based on the current research on time-step setting in military simulation, a trajectory spatiotemporal intersection calculation model is designed to address the performance bottleneck caused by the minimum time step, thus removing the constraints imposed on the minimum time step by interactions such as high-speed target detection and jamming. Experiments involving detection interaction scenarios are designed to verify the effectiveness of the model in preventing missed interactions and improving simulation efficiency.

Key words: time-driven, time step, time-sensitive interaction, simulation efficiency, military simulation
