Abstract:

The core of battlefield electromagnetic environment is electromagnetic environment calculation. Two-dimensional propagation is considered in PE model. Terrain profile acquisition on GRID is the basis for three-dimensional electromagnetic environment calculation on PE model. The three-dimensional electromagnetic environment calculation method based on GRID digital elevation model is given. The method is divided into terrain profile partition, profile parameters acquisition and calculation, three-dimensional electromagnetic data generation and multiple radiation source electromagnetic environment superposition.  The two-dimensional PE model is extended to three-dimensional in laying the foundation for the simulation software design.
