Abstract

The invention discloses an electromagnetic wave reverberation chamber and solves the problem that an existing electromagnetic wave laboratory cannot meet high field intensity and system level test requirements. The electromagnetic wave reverberation chamber comprises a horizontal stirrer and a vertical stirrer. The horizontal stirrer comprises a horizontal rotating shaft and at least one group offolded blades, wherein each group of folded blades are in a V shape, and forms an opening angle in the direction vertical to the horizontal rotating shaft. The shaft of each group of folded blades isvertical to the horizontal rotating shaft; and the horizontal rotating shaft passes through the center of the each group of folded blades. The vertical stirrer comprises a vertical rotating shaft andat least one group of tooth blades. Each group of tooth blades forms an opening angle of 90 degrees, has tooth edges, and opens in the horizontal direction. The shaft of each group of tooth blades isvertical to the vertical rotating shaft. One end of the shaft of each group of tooth blades is fixedly connected with the vertical rotating shaft. The electromagnetic wave reverberation chamber effectively solves the problem of a lot of equipment level and system level electromagnetic compatibility assessment and improves technical level and test capability.

Description

technical field [0001] The invention relates to the field of electromagnetic compatibility, in particular to an electromagnetic wave reverberation chamber. Background technique [0002] The electromagnetic compatibility laboratory has been undertaking the electromagnetic compatibility test task of military products. At present, the electromagnetic environment field strength of the test equipment that needs to be undertaken is greater than 200V / m. The test conditions of the existing electromagnetic compatibility laboratory cannot effectively meet the requirements of high field strength and System-level test requirements. The reverberation chamber is a shielded chamber with a large size and a highly conductive reflective wall. A mechanical stirrer or tuner is installed in the chamber. The boundary conditions of the chamber are changed by the rotation of the stirrer, thereby forming a Statistical homogeneous, isotropic electromagnetic environment. The current reverberation ch...
