摘要
The main problem in ultrasonic nondestructive testing systems is to cancel out effects of the noise from the surroundings. Some measures have to be taken so that the original signal is not prone to mixing with environmental noise at any working condition. Some of these measures are not sufficiently effective, that is why some of these measures are combined in the same system and the amount of calculations (and the same signal processing time) considerably increases. The wavelets transform based methods are widely used for noise reduction in recent time. These methods have statistical optimality properties. The wavelets transform based signal processing method for ultrasonic nondestructive testing systems is suggested. Execution of this method requires fewer amounts of calculations than classical methods.
