Abstract

Abstract:

The emergence and rapid development of UAVs make the target detection of UAV airborne radar in combat simulation great research valuable. In the existing combat simulation platforms at home and abroad, the detection relationship between radar and target is pairwise interactive, and the calculation overhead increases linearly or ultra-linear following the increase of entity numbers, which is difficult to carry out the large-scale real-time combat simulation. Based on the concept of three-dimensional meshing, an airborne radar target detection simulation method is proposed, which can quickly judge the success or failure of detection by making a detection template before simulation to query the template and carry out brief calculation in the simulation. The method effectively reduces the calculation cost of detection and provides a strong support for large-scale real-time combat simulation.

Key words: combat simulation, airborne radar, target detection, three-dimensional divided meshes
