在分布式半实物环境中，从工程实践的角度出发，基于数据分发服务（DDS）建立高性能弹道仿真环境。通过设计并实现仿真步长自适应的方法，进行实时弹道仿真计算。针对分布式半实物仿真环境的特点，提出了基于攻击机仿真环境和基于目标机仿真环境两种仿真方式。在采用同一种弹道仿真模型的情况下，通过对比分析两种方式的仿真实验结果，基于目标机仿真环境的方式稳定地提高了仿真计算频率，因此仿真结果精度较高，从而很大程度上提高了半实物仿真环境下实时弹道仿真的可信度。
Abstract
The creditability of missile trajectory simulation model is not taken into a count based on the distributed environment of hardware-in-loop. From the view of engineering and practice, a strategy of self-adaptation of the simulation step size is designed and implemented in the real-time trajectory simulation. At the same time, two methods of missile trajectory simulation are presented according to the features of the distributed environment of hardware-in-loop: the simulation based on the environment of attacker and the simulation based on the environment of target aircraft. After analyzing the simulation results obtained from the two methods, the missile trajectory simulation based on the environment of target aircraft outperforms the one based on the environment of attacker. Undoubtedly, it has improved the creditability of real-time trajectory simulation in the hardware-in-loop environment to a great extent.
