| Abstract: | The mathematical model of the multi-dimensional data represented by radar map is discussed to solve the problems existing in the radar-map analysis. The geometric features of the visual graphic and its applications are analyzed comprehensively. The methods to estimate the accuracy of the presentation based on the visual graphic classifications and define the multi-dimensional data sequence in accordance with weighting based on the related criteria are established, which effectively solve the problems （such as the area that is not unique） existing in the traditional radar map analysis. |
