In the last two decades, microwave imaging methods for early detection of possible tumors have received ample amount of attentions. As a non-ionizing radiator, the microwave imaging has a definite advantage over X-ray mammography which is currently the main method of breast cancer diagnosis. This paper presents a focused synthetic radar imaging approach to detect the possible existing tumors and to clearly identify their sizes and locations to assist the physicians in cancer prognosis. Both analytical and simulation results are obtained for assumed tumors of different sizes and locations. This is done by modeling the breast tissues and the design of illuminating antenna. Finally, the proposed study includes the required design elements of the optimized antenna used for accurately locating the tumors within a minimal margin of error.
