The existing massive electromagnetic compatibility examination data many takes the carrier by the paper,its essential frequency spectrum data cannot apply directly in the electromagnetic environment forecast and appraisal.In order to solve in the examination report frequency spectrum diagram of curves to transform into the electronic data demand,this article proposed one transformation method,which unified the traditional copy and the computer technology to transforms the screen coordinate into the actual coordinate by coordinate transformation technology,then used traces and the interpolation algorithm to transform the frequency spectrum diagram of curves into the multi-dot frequency-scope discrete data.Based on this principle,it has developed the corresponding pattern recognition software.By validation,range error is less than 3 dB.
