Method and system for faster assessment of sound speed in fluids using compressive sensing technique

A sound speed assessment system, comprising:

• a memory storing instructions;
• one or more communication interfaces;
• and
• one or more hardware processors coupled to the memory via the one or more communication interfaces, wherein the one or more hardware processors are configured by the instructions to:
• receive one or more excitation signals and one or more quadrature signals generated corresponding to the one or more excitation signals from a fluid container containing a fluid, wherein the fluid container is with an inner wall-to-wall distance ‘D’, a wall thickness ‘d’ and equipped with one or more piezo electric transducers placed outside a container wall of the fluid container, for exciting the fluid kept in the fluid container, wherein the one or more piezo electric transducers generate the one or more excitation signals and corresponding one or more quadrature signals by exciting the fluid with one or more frequencies associated with one or more random samples,
• transmitting the generated one or more excitation signals and the one or more corresponding quadrature signals to the sound speed assessment system using a network that is coupled to and in communication with the sound speed assessment system and the fluid container;
• create a pseudo analytic signal vector based, at least in part, on the one or more excitation signals and the one or more quadrature signals using a pre-defined vector creation formula;
• estimate a pulse-echo view by applying a compressive sensing technique over the created pseudo analytic signal vector and the compressive sensing technique reconstruct the pulse-echo view for an original high-resolution spectra, wherein the pulse-echo view is a vector;
• determine whether the estimation of the pulse-echo view is successful based on a pre-defined criteria;
• and
• calculate a sound speed in the fluid based on the determination using the pulse-echo view and a pre-defined sound speed calculation formula.
