Abstract: In order to solve the three-dimensional visualization problem of the radar detection range, this paper gives an algorithm of projection grid for cover fusion（FatPig）. The algorithm designs a smaller-area and appropriate-length grid in the overlapping regions of multi-radar covers, then makes the horrent and tilted projection for each pair of radar covers, in order to gradually filter more detection points in the overlapping area and less detection points out of the overlapping area, finally, gets the fusion of multi-radar covers at a lower computational complexity. It uses the method which needs to compare with the standard comparison libraries of overlapping detection points for gaining the optimal length of the grid, and uses the strategies of projection by pairs for reducing the computational complexity from a macro perspective, which can overcome the high computational complexity shortage of former algorithms. It analyzes the computational complexity and validity of FatPig by experience.
