Airbus Defence and Space develops, maintains and operates systems for civilian and military security authorities around the world. Reliable operation in hostile electromagnetic environments is a must, and so military standards specify precise methods of testing. Their products are tested in accordance with the recently updated MIL-STD-461 EMC standard, which defines the precise set-up of the testing chamber. The effect of the change to the standard needed to be analyzed in order to ensure that the results of compliance testing remained accurate.
Airbus used the CST Studio Suite to evaluate the effect of the change in standard and verify the accuracy of virtual prototyping. By supplementing the testing process with EM simulation, Airbus were able to characterize their anechoic chamber and verify that the redesigned test chamber gave more accurate results. Measured and simulated results from the test chamber agreed closely, increasing confidence in both physical and virtual prototyping.
