摘 要：建立了几个军事短波通信系统仿真模型，并简要叙述了军事短波通信系统中跳频、扩频的干扰方程。文章给出了仿真物理结构图以及功能模块图，也给出了军事短波通信抗干扰性能仿真评估的指标，提出了利用云模型及云不确定性推理对仿真结果进行评估，并给出了干扰和无干扰条件下军事短波通信的抗干扰性能评估结果。-Abstract: A number of military HF communications system simulation model, and a brief description of the military short-wave frequency-hopping communication systems, spread spectrum interference equation. In this paper, simulation of the physical structure and function module map also gives the military a short-wave communications simulation to assess anti-interference performance indicators, the use of cloud model and the cloud of uncertainty reasoning to assess the simulation results are also given interference and non-interference under the conditions of military HF communication the results of the assessment of anti-interference performance.
