High resolution microwave image is obtained form backscattered microwave fields of a rotating conducting circular cylinder, diameter of one meter. The measured backscattered data are taken as angle steps of 0.2 degree intervals for 12.8 degree rotation and 512 different frequencies having 4MHz intervals from 8.176GHz to 10.224GHz. Synthetic aperture processing and pulse compression are accomplished by discrete Fourier transforms implimented by FFT algorithm. From these 512×64 measured data, we obtain one frame image. Repeating 24 times above procedure, 15 degree intervals for 360 degree rotation. 24 independent images identified by different viewing angle of circular cylinder are produced. Summing these 24 image frames, a circular cylinder image is obtained with resolution of three wave lengths (approximately 11-12 centi-meters) and side lobe level is less than-10dB.
