Claim 10:
11. A method for locating a target in situ, comprising the steps of:
emitting pulses of ultrasonic energy waves having one or more frequencies ranging from 100 kHz to 1 MHz by an excitation transducer, wherein an average wavelength of said ultrasonic energy waves is greater than a size of the target,
wherein said ultrasonic energy waves are approximately collimated in a volume away from an aperture; and

receiving, by a sensing transducer, a component of the pulses of the ultrasonic energy waves emitted by said excitation transducer after reflection from the target,
wherein said component of the pulses of the ultrasonic energy waves has an average wavelength greater than the size of the target and is related to a position of the target.
