International audienceWe proposed a method of deconvolution to correct recorded signals from distortion due to experiments devices. In a first time, the approach deals with the construction of an experimental global filter which characterizes all the effects of the acquisition system. The built of the experimental filter is carried out thanks to a family of signals emitted in a finite number and at different frequencies. The knowledge of the instrumental filter allows the deconvolution of recorded signals. This method of characterization is applied to transmitted and reflected signals, recorded in an acoustic tank. We were thus able to construct the global instrumental filter associated with the experimental device set up. The results of th...
