Abstract
Through analysis of the electromagnetic occultation algorithm in which Facets are grouping by the overlapping area of facets projection and grid, and occultation is judged among the facets in the same group. The paper puts forward facets grouping electromagnetic occultation algorithm based on mesh size. In the algorithm, the facets are grouping by the location of the grid which facet central points project into, so the calculation of the overlapping area between facet projection and grid is abridged; occultation is judged by the overlap and the depth of field along the direction of the incident wave, the search domain is extended by the mesh size in order to avoid the absence of sheltered facets located in the edge of grids. Finally, the article takes 2 typical examples to analyse the efficiency of the algorithm, the results indicate that the algorithm is efficient.
