为了准确反映空地导弹数据链高速变化的通信环境特征,文中提出一种结合机动和干扰仿真的效能评估方法。首先建立了包括平爬升、俯冲等7种常规动作的战斗机机动模型,以及4个典型阶段的空地导弹机动模型;其次建立了考虑天线自适应调零和波束控制的数据链干扰信噪比模型。通过仿真实例得出结论:相比弹载终端,干扰机载终端能够取得更好效果。最后,通过仿真实验对干扰机的配置位置进行了优化。

Aimming to accurately reflect the characteristic of communication environment when data link solution is in high speed moving with Air-to-Ground Missile. The article put forward a new tool for effectiveness evaluation, which combines maneuver and simulation of interference. Firstly, build not only maneuver modles of fighters including seven normal movements such as tipping up and sharply diving, but also maneuver modles of Air-to-Ground Missile including four clarify stages. Secondly, build signal-noise ratio modles of the interference of data link discussing adaptive antenna and beam steering. Moreover, draw a conclusion by simulation examples: interference solutions equipped in planes achieve better results than in missile. Finally, optimize the configuration location of jammers through the simulation experiment.
