Abstract
A microwave imaging sensor is disclosed which is resilient to background and skin clutter. Resilience is obtained by cancellation of skin reflections without mechanical displacement of the microwave antenna array or the subject, by utilizing reflections from other antennas and compensating for differences in propagation. The cancellation takes into consideration the expected strength of the reflection at different points in time and for different pairs, in order to minimize the effects on the image, and particularly on image reconstruction of symmetric targets.
Claims21
A method for enhancing microwave imaging of an object, comprising:
- collecting microwave responses for multiple combinations of transmit antennas and receive antennas;
- performing an estimation skin reflection, where the estimation for an antenna pair is based on signals received from another antenna pair during a measurement;
- performing a cancellation of the skin reflection based on the estimation to obtain at least one corrected signal;
- and
- generating an image from the at least one corrected signal after the cancellation.
