摘要：

The problem of visual discrete GTD (geometrical theory of diffraction) ray path tracing on aircraft is investigated. Quickly-3D-model for electronic countermeasures aircrafts is carried out based on OpenGL. The model provides surface discrete grids data. Enough points can be achieved by minutely modeling or interpolating splines and nodes. According to Fermat principle, the length of geodesic path is calculated with the method of dynamic programming on the platform surface discrete grids served as. Visual discrete GTD ray path tracing on aircraft is realized with the method of recursive dynamic programming. This work provides an approach for quickly analyzing antenna isolation degree on early warning aircrafts, strategic reconnaissance aircrafts and electronic support aircrafts.
