System and method for detecting of electric device

PURPOSE: An electronic device detection system and a method thereof are provided to reduce an electronic device detection error. CONSTITUTION: An electronic device detection system(100) includes a training data storage unit(102), a high frequency wave measurement unit(104) and a determining unit(106). The training data storage unit stores an electronic device training data group and a metal training data group. The high frequency measurement unit generates measured data by measuring intensity of the second high frequency and the third high frequency of a target object. The determining unit determines a group in the electronic device training data group and the metal training data group where the measured data is included.
