And the analytic calculation method of the selfradiation impedance and mutual radiation impedance of the transducer array is studied.

Their cost varies from $150 for a self-assembled kit to $4,000 for a more sophisticated version that stores radiation readings along with the GPS coordinates of where those readings were taken.
