Method and system for constructing virtual-real fusion space electromagnetic environment based on LVC

The invention provides a method and a system for constructing an electromagnetic environment based on an LVC virtual-real fusion space. The method comprises the following steps: acquiring acquisition data in a target physical space; the acquisition data comprises equipment acquisition sub-data and environment acquisition sub-data; inputting the collected data into a pre-constructed virtual model for simulation training to obtain a trained virtual model; carrying out multi-source heterogeneous data fusion on the obtained real equipment data, simulator data and construction simulation data in the trained virtual model through a plurality of interaction modes and a real-time feedback mechanism; and unifying time steps by using a simulation engine, simulating an electronic countermeasure environment in real time according to the multi-source heterogeneous data, and providing a feedback result. According to the method, the problem that the fidelity is not high due to the fact that virtual-real fusion based on LVC
