Ultra wideband hemispherical microwave imaging system

Abstract

This paper has reported an automated high resolution hemispherical imaging system using ultra wideband microwave signals. At present, the system operates in the monostatic radar mode. To achieve a hemispherical scan, the imaged object is placed on the turntable (rotational axis) for a 360° scan while the elements of the array antenna are fixed and suitably spaced in vertical and azimuth directions. The operation of this system has been illustrated in an example of a simple breast phantom.
