Abstract

Abstract:

In order to represent the invisible electromagnetic environment to commander, the volume visualization based approach of electromagnetic environment in virtual environment is proposed. First, this approach uses the LongleyRice radio propagation model to calculate 3D electromagnetic power volumetric data. And then the data is rendered on virtual environment using coordinate transformation based on hardwareaccelerated volume visualization. Finally, electromagnetic environment of different power is classifiably represented using color mapping tool. The results of the experiment show that this approach can visualize the inner detail of electromagnetic environment, and provide decision supporting and electromagnetic equipments planaiding for users.

Key words: volume visualization, electromagnetic environment, digital globe, virtual environment
