摘要
在理论分析的基础上，结合对大量试验数据的分析，给出了空基型导弹图像传输系统无线窄带信道的基本模型。该模型由直视分量、地面镜面反射分量和散射分量三项构成，根据飞行区域不同的地形特征，在该模型中镜面反射分量能量是直视分量能量的5％～56％，而散射分量能量约为直视分量能量的1％～8．4％。
Based on the analysis of theory data, this paper brings the base model of wireless narrow-band channel for air-based missile image transmission system. This model consists of direct sight heft, ground reflect heft and scatter heft. According to the terrain character of flight region, the ground reflect heft is 5% - 56% of the direct sight heft, and the scatter heft is 1% -8.4% of the direct sight heft in this model.
