PROBLEM TO BE SOLVED: To solve the problem that an operator is hard to understand a blind spot in a space since a conventional radar coverage display device divides altitude into several sections, to calculate a region that is obstructed by a topographical bulge and a structure in advance, which is projected on a two-dimensional map for each altitude section, to be displayed.SOLUTION: A particle in a first semi-transparent color is made to move linearly in elevation and orientation which are decided at random from a certain position, and when collision with an obstacle is detected, the color of the particle is changed to a second semi-transparent color. By drawing particles in a three-dimensional space, a perspective region and a non-perspective region are painted differently in a space, to allow a blind spot in a radar coverage to be spatially imaged.SELECTED DRAWING: Figure 2 |
