Method and system for object localization |
| 摘要 |
This document describes a method and system for object localization. In accordance with the method an object (1) is illuminated by at least one first type of signal, and response of the signal is detected. In accordance with the invention the object (1) equipped with a transponder (2, 3) backscattering the first type of signal, the transponder (2, 3) is illuminated also by a second type of signal affecting to the backscattering frequency of the transponder (2, 3), and the backscattered signal from the transponder (2, 3) is detected in order to localize the object. |

1. A method for object localization comprising the steps of:
illuminating an object by at least one first type of signal, detecting a response of the signal, wherein the object is equipped with a transponder for backscattering the first type of signal, illuminating the transponder by a second type of signal that modifies a backscattering frequency of the transponder, and detecting the backscattered signal from the transponder, the backscattered signal being associated with the second type of signal and having a modified backscattering frequency, the backscattered signal from the transponder being used in order to localize the object. |
