Research on moving target tracking scene simulation technology under battlefield complicated environment based on Vega

In order to better simulate the real environment of the battlefield, which has moving-target and the complicated background and to simulate the tracking process of the target with 3d´s simulation. This paper introduce a development platform of the Vega 3d simulation software, and how to use the Vega to simulate the complex battlefield background, which has the sky, the explosion effects in the ground, the fly parameters of fighter planes. It reappear a complete process, which contains capturing target and tracking target. Experiment indicate that the Vega development platform is convenient and fast, and can achieved the design parameters for the task´s demands. It also has many advantages, that contains repeating the performance of real experiment and reducing the expenses of the military experiment.
