Systems and methods for performing diagnostic sonography. Ultrasound information of a subject region can be collected. The ultrasound information can be based on one or more exponentially swept ultrasound chirp pulses transmitted toward the subject region and backscatter of the subject region from the one or more exponentially swept ultrasound chirp pulses. One or more corresponding harmonic responses and a corresponding fundamental response for each of the one or more exponentially swept ultrasound chirp pulses can be separated from the ultrasound information. Further, one or more non-linear properties of the subject region can be identified based on either or both of the one or more corresponding harmonic responses and the corresponding fundamental response for each of the one or more exponentially swept ultrasound chirp pulses.
