Research and Application on Real-time Acquirement Technique of OpenFlight Digital Terrain Based On Grid

Radar system simulation based on digital terrain is a new foreground of radar simulation. However, acquirement of enormous terrain data becomes a difficulty in radar simulation which influences the real time of simulation. The paper analyzes the limitation of structure of openflight digital terrain in radar simulation in detail. A new method for transforming terrain data to grid data is put forward. The method is applied to the design of a certain airborne radar simulation. It is shown that the method successfully solves the problem of digital terrain acquirement and improves the system performance
