ABSTRACT
A wide band FMCW radar has been used for microwave synthetic aperture imaging of objects embedded in dielectric medium. Initial images formed the system where highly distorted due to numerous phase errors, the system has been calibrated through the use of a number of different calibrations. The two main types of errors are (1) the hardware system itself and (2) the phase terms in the received signal. The errors were eliminated by either changing the hardware system or developing a suitable algorithm in software to account for the error in the system. This system will be used for nondestructive evaluation and ocean wave scatterometery experiments.<>
