  In this paper, we present a unique $\text {2D}$ high resolution, compact,
low-cost, low-weight, and highly accurate millimeter wave imagery system
capable of operating in all weather conditions. We describe millimeter wave
imaging process in detail and present several novel signal processing methods
with their applications. To create the array, we utilize the Synthetic Aperture
Radar (SAR) concept. The imagery system presented in this work, can strongly
compete with Lidar systems as the resolution limit is at the same level.
Furthermore, in contrast to the Lidar systems, our imagery system can operate
in heavy rain and dense fog and produce high quality images.
  We use our custom-made Frequency Modulated Continuous Wave (FMCW) radar
operating at W-band with $\text {33 GHz}$ bandwidth for data collection and
present the results.
