Visualization of 3D spatial data sets applied in radar imaging

Radar imaging technology is a vigorous research field at present. The method of SAR imaging is often used in radar imaging. But it is a quite complex process. In this paper, visualization of 3D spatial data sets technology is applied in radar imaging. The principle of creating iso-surfaces in 3D regular data sets and the optimization to MC algorithm are introduced. The way of building programming circumstance for OpenGL to render iso-surfaces is presented in detail. Real data get from radar scanning is used to implement 3D re-building. The result is quite satisfactory because the configuration of spatial object and the reflective intensity to electromagnetic wave are reflected well.
