Echo image generation method for marine radar based on OpenGL modeling and simulation technology

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.
