Abstract

Imaging modalities used for breast cancer detection currently are not sufficient for society's need. Microwave imaging has gaining a lot of consideration among researcher due to accurately tumor detected and effective treatment with low cost especially for early cancer detection. UWB radar that based on microwave imaging for early breast cancer detection is one of the most attractive and promising modality lately under investigate. The main point for using microwaves technique for tumor detection which is by the observation at microwaves frequencies, the dielectric contrast of permittivity and conductivity between normal and malignant tissues. This project focuses on the experimental of reflection coefficient in complex frequency domain is obtained using Vector Network Analyzer (VNA N5242A) right after the RF Horn antenna is exposed to the breast phantom. VNA enable the time domain approaches instead of common frequency domain measurement. Through this modality, a breast(cooking oil and stone) is illuminate from various point with short UWB microwave pulse that is generate by RF Horn antenna with frequency of l to I 0 GHz and the collected backscattered energy is being analyze to identify the presence and location of the cancerous tissue. Time domain simulations by two different experimental setups are performed. Here, the MIST beamforrning algorithms have been applied for this study to the numerical data generated by VNA to get the tumor location.
