Abstract
A method for detecting a target or targets in a medium. The method incorporates generating beams of ultrasonic wave energy each having a modulation envelope and causing each beam of wave energy to impact a target region having a multiplicity of targets and demodulating each signal generated by vibration of each target caused by the interaction of a respective ultrasound wave energy beam having a modulation envelope with each of the targets and receiving each demodulated signal from each target by a multiplicity of sensors. Thereafter, each time-of-flight of each demodulated signal from each of the targets to each of the multiplicity of sensors is computed to determine the location of a respective target.
