Cylindrical Volume Rendering on Radar Propagation Information in Complicated Environment
Radar propagation information is an important basis for the analysis of radar performance,and it′s represented using visualization,so that radar propagation can be analyzed in complicated environment quickly and effectively.This paper presents a novel hardware-accelerated cylindrical volume rendering approach on visualizing the radar information in complicated environment.3D radar volumetric data is calculated based on advanced propagation model(APM),which takes into account the effects of irregular terrain and atmosphere,and it′s able to accurately predict the effects of the radar transmission.Taking full advantage of the current graphics hardware programmability,we extend direct volume rendering method through coordinate transformation in graphics hardware to sample the radar volumetric data.The real-time cylindrical volume rendering of radar propagation information is achieved.And radar propagation information is classified displayed by assigning different color and alpha through color picker.The result show that this approach is suitable for radar performance analysis,and can effectively support the design and deployment of the radar.
