摘　　要：为解决当前航海雷达仿真器中雷达回波图像不真实问题,以岸线为例提出基于OpenGL建模技术的模拟航海雷达回波的新方法,研究雷达回波图像生成技术,给出雷达岸线回波及雷达岸线回波图像的生成算法.对RGB、HIS颜色模型在模拟雷达回波强度上的应用进行探讨,给出目标回波强度的数学模型.通过加入噪声模型,实现航海雷达岸线回波仿真,其结果与电子海图显示基本相符.To solve the problem of falsehood of radar echo image in marine radar simulator at present,taking the coastline as example,the method to simulate marine radar echo based on OpneGL modeling and simulation technology was put forward.Radar echo image generation technology was studied,and generation methods for radar coastline echo and its image were given.The coastline echo intensity model based on RGB and HIS color models was presented.The marine radar coastline echo simulation was realized by adding yawp model.Results show that the simulation image is consistent with that of electronic chart.
