The environment electromagnetic noise eliminating method base on self-adaptive filter

According to the interfere of environment electromagnetic, a Self-adaptive noise counteract method is put forward. Making use of double channels signal's pertinence, the environment electromagnetic noise is controlled and attenuated by transverse filter parameter regulating, and improving SNR quality is realized. Base on the method above, the complex electromagnetic environment measuring and analyzing system is opened out, and then, the method is validated though simulation and outfield measure. As a result, the environment electromagnetic noise eliminating method base on self-adaptive filter is effective to avoid the noise and distill the EUT electromagnetism radiant signal.
