MICROWAVE IMAGING RESILIENT TO BACKGROUND AND SKIN CLUTTER

摘要

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.
