Summary

As far as instrumentation for microwave imaging is concerned, it should be mentioned that illuminating-receiving systems are essentially based on two different approaches. The first one concerns the use of one or more probes operating in a real or synthetic mode. The second approach involves the use of passive probes that are sequentially modulated. Scanning systems for tomography are often composed of circular arrays of antennas. This chapter considers the configuration of one of the first proposed imaging systems working at microwaves, namely, the scanning system developed for medical purposes at the Polytechnic University of Catalunya, Barcelona, Spain. Concerning the transmitting and receiving antennas for imaging systems, the choice depends again on the configuration. Several tomographic systems use dipoles, which ensure a wide beamwith in the azimuthal plane and an acceptably narrow beamwidth in the elevation.
