Abstract

The invention discloses a phase stirring reverberation chamber, a testing device and a testing method. The phased-array antenna is placed in the reverberation chamber cavity, the to-be-tested device is placed in the testing area in the reverberation chamber cavity, the phased-array antenna is used for carrying out beam scanning to change the state in the reverberation chamber, a field with uniform statistics is formed in the testing area, and the effect of a mechanical stirring device can be achieved in the reverberation chamber; the method which is high in operability and low in cost is provided for electromagnetic compatibility simulation and testing in the reverberation chamber. The testing process does not need a mechanical stirrer, so that the volume of the reverberation chamber cavity can be reduced and the volume of the testing area can be increased. And meanwhile, the device has the characteristics of high speed and easiness in operation, and can be widely applied to the condition of carrying out EMC test on a conventional reverberation chamber.
