3D radar - Modeling virtual maritime environment For the static environment perception

摘要

Electromagnetic propagation has been a subject of interest, mostly in applied physics research and atmospheric physics over many decades. Contributions have been more towards more theoretical rather than experimental. With the advancement of radar and laser technology and regular use in achieving military related objectives, electromagnetic wave propagation has now become a matter of interest to computer scientists. Today's military services have faced challenges of maintaining financial stability of training activities. Thus most of them focus into computational simulators can be used as a safe alternative in a cost beneficial manner. Considering field of military, radar simulators plays important role in simulations. This research focuses on simulating sea-born radar for 3D virtual maritime environment. Proposed approach takes the 3D environment as the input and maps the objects via electromagnetic wave properties. It captures the surrounding objects and gives the 2D visualization of the 3D environment as the end result. In the static environment perception both radar and environment are considered to be stagnant. This approach uses efficient techniques to achieve a 2D visualization of the 3D environment by embedding electromagnetic wave properties like reflection, refraction, polarization, diffraction and attenuation in wave propagation. Realism has been incorporated in the model by capturingoptimization techniques.
