For the correction of the students' radar plotting analyzing results in the radar plotting training in this college, if there is any incorrect answer in the analyzing process, the instructor will strictly examine the incorrect parts and search for the cause from the value and diagram. He/She will then give the student the feedback of the analyzed data. However, the current method is proved to be extending the training time dramatically. Therefore, in order to make the correction more efficiently, I have done a few studies on the correction supporting system. Besides that, I have also used a prototype system to confirm its effectiveness. The outline of this system is it digitalized the radar plotting sheet, which the answer was written on it, by scanner and have the computer support the examination of the answer. We have launched a few tests on the system to find out its effectiveness. For the result, the time for correction is 20 seconds/piece, and the accuracy is 100%. Although human being need only 20 seconds to analyze a piece too, they need around 10 minutes to analyze the cause for a single piece of radar plotting analyzing result. From the situation above, we know that this system have the ability to analyze the result as fast as human being or even faster than human beings from the test. Therefore, its effectiveness is proved.
