Abstract :
This paper presents an efficient method of millimeter wave (MMW) image formation using synthetic aperture radar (SAR) modeling. A commercial vector network analyser (VNA) transmits and receives the signal centered at 35GHz. The MMW signal illuminates and reflects off the surface of the target. The collected signals from VNA are processed under the MATLAB environment. Experiment results show that MMW imaging using SAR modeling not only improves the angular resolution but also provide better reconstruction result.
