In addition, the detection device 34 of the electronic warfare equipment 30 identifies the azimuth angle and the signal type of the threat element based on the setting values for the electronic warfare equipment 30 received from the control computer unit 10.

However, the electronic warfare equipment 30 is an independent equipment which is the object of the performance test and the failure detection check in the performance test and failure detection check system 100 of the electronic warfare equipment according to the present invention, and means a general electronic warfare equipment, More specific structure and performance will be omitted since it is obvious to those skilled in the art.
