A device is disclosed that, in an illustrative embodiment, includes an input line, a main gain component, a first local gain component, and a second local gain component. The main gain component, the first local gain component, and the second local gain component each have a communicative connection with the input line. The main gain component is configured for applying a main gain to an ultrasonic wave signal received via the input line, thereby providing a main gain signal. The first local gain component is configured for applying a first local gain to a portion of the ultrasonic wave signal within a first signal gate, and thereby providing a first local gain signal. The second local gain component is configured for applying a second local gain to a portion of the ultrasonic wave signal within a second signal gate, and thereby providing a second local gain signal.
