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.
