Abstract

The invention provides an electromagnetic emission point positioning method based on an urban environmental physical model. The method comprises the following steps: 1) establishing an urban digital three-dimensional model; 2) based on the principle of a mirror image method, establishing a model of the urban electromagnetic environment by utilizing a ray tracing kernel function in a toolbox of Matlab; 3) setting an electromagnetic emission point in the established urban electromagnetic environment model, collecting corresponding DC data, and training a pre-constructed machine learning model byusing the DC data as a sample to obtain a trained model; and 4) measuring real DC data at a set position in a real city environment, and inputting the real DC data into the trained model to identifythe position of the electromagnetic emission point. By applying the embodiment of the invention, the requirement of rapid modeling of the urban electromagnetic environment can be well met.

Description

technical field [0001] The invention relates to the technical field of urban electromagnetic environment simulation, in particular to an electromagnetic emission point positioning method based on an urban environment physical model. Background technique [0002] The electromagnetic spectrum is the sixth independent combat domain after land, sea, air, space, and cyberspace, and cities are the main battlefields of future land warfare. Therefore, in future urban operations, the competition for the electromagnetic spectrum will be the key to victory in wars , and the electromagnetic environment situation is the most important information in the electromagnetic spectrum. At the same time, in wireless communication, the study of urban electromagnetic environment is very important, because the distribution of urban buildings is usually relatively dense, a large number of wireless communication devices are filled in modern cities, and a large number of mobile communication base stat...
