Abstract: Information countermeasure technology is a wide-aperture comprehensive subject which integrates computer science, information science and communication science. However, at present, there is no integrated experimental system of reconnaissance and jamming countermeasure with engineering applicability for the experimental courses of communication countermeasure and radar countermeasure at signal level. In view of the shortcomings of this course, this paper designs a comprehensive experiment with practical engineering application, which can cover the completion of radar/communication signal interception simulation, direction finding, parameter estimation, type identification, jamming style design and jamming effect evaluation, etc. The experiment and the construction goal, specific content and implementation plan of the experiment are expounded. The practical effect from the first year of teaching reform shows that this comprehensive experimental course can stimulate students’ interest in solving engineering problems, enhance students’ flexible use of multidisciplinary knowledge, and achieve good teaching results.
