Based on the working principle of optical payload of shipborne UAV and characteristics of the environment of shore target, the concepts of angle for observation, longitudinal slope and lateral slope of shooting observations are proposed, and the calculating models of longitudinal slope, lateral slope and resettlement are constructed. Based on the simulation of resettlement area of optical payload, the concepts of distortion of longitudinal resettlement and lateral resettlement at different visual field angles, average slopes and view axis angles, by the method of exploratory analysis, on the light of the nonlinear relationship of the four features, which can be used for opration and training.%基于舰载无人机光电载荷工作原理和岸上目标环境特点,提出了对岸射击观测的观测角、纵向坡度和横向坡度的概念,建立了纵、横向坡度和对岸收容面积计算模型；基于对光电载荷对岸收容面积的仿真,给出了对岸纵、横向收容畸变率的定义,构建了相应的计算模型；提炼出了影响对岸收容畸变率的四个因素,针对这四个因素之间的非线性关系,采用探索性分析方法,给出了针对不同的视场角、平均坡度和视轴俯角下对应的满足纵、横向畸变要求的观测角范围,供作战和训练时查用.
