In this paper, firstly we researched the relationships of the communicating distanceand the channel characteristic, the effect of the multiple scattering to the laserpropagation, the requirement of the laser communication to the ATP system and theway to determine the angular dispersion and receive field of view. It is proved that inlight haze weather, letting the input and output laser\'s wavelength are diferrent witheach other, after passing by the filter, it can avoid backward scattering effectually andfor the communication within 15km, the influence of the multiple scattering inatmosphere can be ignored.

A new approach to eliminate the ranges dependence based on angular frequency shifting in space domain was presented, in which, the nonhomogeneity of clutter is removed and the blind area of target detection is reduced due to the fact that the clutter of all the compensated range cells in every channel is moved to the place of the clutter of the desired cell by the different angular frequency shifts being added into spatial data along all Doppler channels for every compensating range cell.

第七章针对非正侧视相控阵机载雷达，由于杂波在距离上呈现出严重的非均匀性，尤其是在近程这种依赖距离的杂波谱呈现的非均匀现象更为严重，使得用于计算自适应权的协方差矩阵不可能直接由距离单元数据统计平均来估计得到，否则STAP处理及其降维技术难以获得理想的杂波抑制性能和目标检测性能，甚至恶化。
