Airborne ultrasonic images are not often used in practice, mainly because of the poor air propagation properties of ultrasonic frequencies and high necessary computation resources. The availability of powerful signal processors and the need to have solutions in some special environments, such as dark, smog or fog, require the reconsideration of airborne ultrasonic images, using classic or classic...
The paper considers the uncertainty modeling and compensation in the context of ultrasonic image generation with fixed working frequency. From the set of uncertainty sources, which could be considered at the level of sonar systems, the present work considers only one source: the uncertainty at the level of the receiver transducers, expressed by two phenomena: side-lobes, possibly slow time variables,...
