Research On 3D Visualization Technology Of Radar Net Detection Range

Battlefield three-dimensional visualization has become a modern war in C4ISR system urgently needs to solve one problem. Both sides electromagnetic situation is an important part of the battlefield. Radar as the main source of electromagnetic situational plays role in information war is more and more big. But radar working environment becomes extremely complex, radar networking technology is an effective measure to solve this problem. How to visualize the battlefield environment of radar detection range and netted radar detection range in the three-dimensional situation has become a battlefield an integral part of the three-dimensional visualization.There are many complex factors can affect the battlefield environment, this article only consider the radar jammer suppression of interference factors. Combined with the actual project application, this article mainly around two solution which is undisturbed and disturbed where the netted radar detection range of three-dimensional visualization problem and the problem of netted radar detection range of different level visualization. In order to solve these above problems, first, formula derivation and mathematical modeling the radar detection range, so that turn the above problems into math problems, and put forward the two kinds of different algorithms. Among them, The first algorithm based on Boolean operation between the structure of Nef polyhedral which defined in the computational geometry algorithms library, CGAL, this algorithm is versatility and real-time weaker. The second algorithm based on triangular mesh intersection algorithm and Delaunay triangle subdivision algorithm, this algorithm is weaker commonality but strong real-time performance; After using OpenGL rendering two algorithms and the test results found that, both of two algorithms results three-dimensional visual effect is good, which can effectively solve the above problems, meet the demand of project application.
