Abstract

Abstract: The battlefield electromagnetic situation has the characteristics of complexity, multidimensions and time-varying. Real-time visualization of battlefield electromagnetic situation is significant for commanders to make scientific decisions. Currently, the battlefield electromagnetic data models are not perfect. A mathematic model of the field strength of multiple radiation resources is established by taking the field strength for example, which is used to provide the data sources for constructing 3D volume data field of the battlefield electromagnetic situation. The traditional central processing unit (CPU)-based algorithm cannot meet the requirement of real-time solution because of the complexity of mathematical models related to the volume data field. A volume data field accelerated generation technique based on general purpose graphics processing unit (GPGPU) is proposed. The experimental results show that the proposed technique can meet the requirement of real-time visualization compared to the traditional algorithm. A transfer function is designed to accomplish the visualization of electromagnetic situation based on GPU ray-casting algorithm.
