Abstract: The 3D visualization of radar detection range is the key component of the display of modern battlefield electromagnetic situation. This paper puts forward a visualization method of radar detection range drawing based on the 3D earth scene. The method is based on the model of radar detection range in electronic countermeasures under ideal conditions and interference conditions, and combines with the coordinates transformation method between the geodetic coordinate system and geocentric coordinate system. By studying and designing a database based on the visualization data requirements of radar detection range under ideal conditions and interference conditions, based on the 3D earth scene platform ArcGlobe and OpenGL technology, we apply the visualization method to develop the marine battlefield electromagnetic situation display system. The experimental results show that the visualization method can accurately and vividly show the radar detection range in 3D earth scene under ideal conditions and interference conditions, and provide support for commanders to insight into the battlefield situation.
