Electromagnetic situation presenting method in the complex electromagnetic environment based on parabolic equation

In response to the electromagnetic (EM) situation in the complex EM environment, a novel presenting method is studied. Firstly, the framework for presenting the EM environment situation is proposed, and the essential characteristics of the EM environment are quantitatively described and analyzed in depth from several aspects; Then, based on the precise perception of the complex EM environment, the standard one-way parabolic equation (PE) model and two-way PE model are studied to solve the forward-propagation and backward-propagation of the EM wave. Finally, the comprehensive presenting system of EM environment situation is designed. Employing color bar visualization techniques, the distribution characteristics of propagation loss under various terrain conditions can be intuitively presented.
