Abstract
A method and system of imaging at least one passive object within a surrounding structure is provided. The surrounding structure has multiple surfaces. The method includes: transmitting an ultrasonic signal into the surrounding structure using an array of ultrasonic transmitters and receiving reflections from the passive object using an array of ultrasonic receivers. The method also includes steering the ultrasonic signal such that it includes at least one reflection off a surrounding structure surface using stored data relating to a position of at least one of the surfaces.
Claims27
A method of imaging at least one passive object within a surrounding structure having a plurality of surfaces, the method comprising:
- transmitting an ultrasonic signal into the surrounding structure using an array of ultrasonic transmitters;
- receiving reflections from the passive object using an array of ultrasonic receivers;
- steering the ultrasonic signal such that it includes at least one reflection off a surrounding structure surface using stored data relating to a position of at least one of said surfaces.

A system arranged to image at least one passive object within a surrounding structure having a plurality of surfaces, the system comprising:
- an array of ultrasonic transmitters arranged to transmit an ultrasonic signal into the surrounding structure;
- and
- an array of ultrasonic receivers arranged to receive reflections from the passive object;
- wherein the system is arranged to steer the ultrasonic signal using stored data relating to a position of at least one of said surfaces such that the ultrasonic signal includes at least one reflection off a surrounding structure surface.

A device for imaging at least one passive object, the device comprising:
- an array of ultrasonic transmitters, arranged to transmit an ultrasonic signal, wherein a pair of adjacent transmitters of said array has a spacing equivalent to a half-wavelength of a sound wave in the ultrasonic frequency range;
- an array of microphones arranged to receive reflections from the passive object, wherein the microphones have a peak response in the audible frequency range;
- wherein the device is arranged to determine an image of said object using said reflections.
