摘要
如何在实际数据和先验知识较少的情况下,建立适用于通信对抗仿真系统的短波天波传输损耗计算模型来为实际系统提供指导,是通信对抗仿真中一个非常棘手的问题。根据信道传输理论,在合理选用和优化各种现有的独力分散数学模型的基础上,设计了一种完整而简洁的短波天波传输损耗计算流程,并针对流程中的每一步给出了详尽的数学模型。该仿真流程和计算模型运用于某实际的C3I仿真系统,由于缺乏详实的实际数据,无法给出短波天波信道损耗计算子模块仿真结果与实际结果的直观对比,但是仿真系统的总体运行结果以及与实际系统的联调结果表明,该部分的计算结果正确,仿真流程与仿真模型有效可行。
In the case of scarce practical data and priori knowledge, modeling of the transmission loss of HF skywave to give guidance to the practical system is a very difficult problem in communication countermeasure simulation system. Based on the channel transmission theory, a complete and concise procedure for calculating the HF skywave＇ s transmission loss is proposed in this paper by using and optimizing the available independent and disperse models reasonably. Additionally, elaborate mathematic models are given according to every step of the procedure. Simulation procedure and calculation methods are used in a practical CaI simulation system. The intuitionistic contrast result between the simulation and practical ones cant＇ t be provided because of the absence of particular practical data, but the whole running and joint debugging results indicate the calculation resuh＇ s correctness and the validity of the simulation procedure and models.
