In this paper, by discretizing the battlefield region, using the power, frequency and direction of the wave to quantitatively characterize the electromagnetic environment, the image similarity measure, the gray histogram comparison and the signal arrival direction histogram method are introduced to analyze the histogram. The degree of change of the graph is proposed, and a calculation method for calculating the degree of change of electromagnetic environment is proposed. The method is simulated. The comparison of the histograms at different time points proves that the method has certain effectiveness in dealing with various electromagnetic environments.
