A method for processing ultrasonic signals acquired by ultrasonic probing comprising the following steps: - controlling a plurality of emission transducers (108 1,..., 108 N) for L successive emissions of ultrasound waves to an area of interest, - controlling N reception transducers (108 1,..., 108 N) so as to simultaneously receive and for a predetermined time, for each successive emission, N measurement signals, particularly measuring noisy echoes due to reflections of the emission in question in the area of interest, - obtaining an array (K(t)) of ultrasonic time signals of the size LxN, each coefficient K i,j (t) of this array representing the measurement signal received by the j-th reception transducer due to the i-th emission, - transforming the time signal array (K(t)) into a frequency signal array (K(ω)), - performing a singular value decomposition of the frequency signal array (K(ω)), characterized in that it comprises a step for denoising (208, 210, 212, 214, 216) the ultrasonic time signal array (K(t)) by: - removing some of the singular values and associated singular vectors obtained from said singular value decomposition according to a predetermined criterion for distinguishing between singular values associated with defects and singular values associated with noise, this criterion relating to successive amplitude differences between singular values in a decreasing series of amplitudes of said singular values determined on the basis of the frequency signal array (K(ω)), - reconstructing a denoised frequency signal array (Kf(ω)) on the basis of unremoved singular values and singular vectors, and - performing an inverse transform of this denoised frequency signal array (Kf(ω)) into a denoised time signal array (Kf(t)). - controlling a plurality of emission transducers (108 1,..., 108 N) for L successive emissions of ultrasound waves to an area of interest, - controlling N reception transducers (108 1,..., 108 N) so as to simultaneously receive and for a predetermined time, for each successive emission, N measurement signals, particularly measuring noisy echoes due to reflections of the emission in question in the area of interest, - obtaining an array (K(t)) of ultrasonic time signals of the size LxN, each coefficient K i,j (t) of this array representing the measurement signal received by the j-th reception transducer due to the i-th emission, - transforming the time signal array (K(t)) into a frequency signal array (K(ω)), - performing a singular value decomposition of the frequency signal array (K(ω)), - removing some of the singular values and associated singular vectors obtained from said singular value decomposition according to a predetermined criterion for distinguishing between singular values associated with defects and singular values associated with noise, this criterion relating to successive amplitude differences between singular values in a decreasing series of amplitudes of said singular values determined on the basis of the frequency signal array (K(ω)), - reconstructing a denoised frequency signal array (Kf(ω)) on the basis of unremoved singular values and singular vectors, and - performing an inverse transform of this denoised frequency signal array (Kf(ω)) into a denoised time signal array (Kf(t)).
