Abstract
The present invention relates to a detection system comprising detection means (140) of the inductive field type and detection means (10) using microwave field-based imaging, analysis means (50) which are suitable for analysing the signals from the inductive detection means (140) and for deducing therefrom the potential presence of the metal targets, and means which are suitable for correspondingly modifying, at least in a zone of interest, the sensitivity of the detection means (10) using microwave-based imaging.
Claims18
A detection system comprising:
- inductive detection means configured to generate signals;
- microwave detection means configured to generate a microwave image;
- and
- analysis means configured to analyze the signals, to deduce therefrom a potential presence of a metal target, to a position of the metal target, and to adapt accordingly a sensitivity of the microwave detection means such that the sensitivity is greater in an area of interest corresponding to the position of the metal target in the microwave image than in other areas of the microwave image.

A detection method comprising the following steps:
- generation of a signal with inductive detection means;
- generation of a microwave image with microwave detection means;
- analysis of the signal;
- deduction of a potential presence of a metal target;
- when a metal target is identified, determination of a position of the metal target;
- and
