Purpose of the paper is to study principle and method to predict electromagnetic compatibility （EMC） in ground radar system. According to requirements to electromagnetic environment and EMC of ground radar system, mathematical model of three basic elements of electromagnetic interference is set up; related calculation is performed; and implementation criterion of EMC evaluation system is determined. Based on system models of each part of ground radar as well as the related data extracted, evaluation to electromagnetic environment efficiency of related radar parts shows that prediction result is basically in coincidence with actual test result, which can provide designer with reference to modify their design scheme.
