Synthetic Array for Radiometric Retrieval of Thermal Fields in Tissues

F. Bardati, M. Mongiardo, D. Solimini

Abstract

The feasibility of reconstructing the thermal field in biological tissues from brightness data measured by an array of microwave antennas is investigated through a numerical simulation. The array does not make use of phase information and is synthesized through the Kalman filter algorithm. The obtained results indicate that, by a multispectral technique, such a synthetic array might be able to achieve spatial resolution not only in a transverse direction, but also in depth.
