3D representation of Radar coverage in complicated environment

The 3D representation of Radar electromagnetic information affected by terrain, ocean and weather is an unavoidable problem in the future digital battlefield. Based on the digital models of the complex environment factors such as atmosphere absorption coefficients, atmosphere refraction index and ground, we used APM model and atmosphere absorption attenuation model to calculate in-plane propagation loss and so to get the 2D in-plane coverage of given Radar. Then we combined these 2D coverage to construct the 3D Radar coverage. The experiment of embedding a typical Radar into digital battlefield showed that the 3D Radar coverage affected by complex environment was vividly and dynamically visualized in time and parameters of Radar and target could be adjusted interactively, which could provide excellent decision supporting and plan-aiding for users.
