摘　　要：提出了一种空地电视制导导弹图像传输系统抗干扰评估的总体框架,建立了电磁干扰条件下系统的抗干扰评估的空间模型。而后基于有限状态机理论,建立了电视制导导弹图像识别模态转换模型,详细讨论了典型干扰对电视图像数据链的影响。最后,应用计算机仿真技术,得到制导系统在不同信噪比条件下导弹的最大作用距离和图像干扰效果。The anti-amming evaluation frame of TV-command-guided image transmission system of air- to-ground missile is put forward. Then space model of anti-jamming performance evaluation is built under the electronic jamming exercises. By Finite State Machine theory, the mode transition model＇ s recognising of the TV-Command-Guided missile is deduced, and the influence of typical jamming in TV-guided system＇ s image data link is discussed in detail. Finally, by the computer simulation technology, this paper gets the missile＇ s longest tactics available distance and image jamming effect in different Signal-to-Noise.
