A high resolution ultra wideband radar prototype is developed for through the wall imaging. The frequency range of operation of the radar is selected to be 1.85 to 6 GHz in order to have high spatial resolution. Besides the hardware, we have also developed a custom image processing software which attacks the problem of false target recognition and rejection. In this paper, we present our protot...

The endodermis surrounds and protects the vasculature partly by depositing hydrophobic suberin in cell walls. Yet, some cells remain unsuberised. These historically termed ‘passage cells’ are assumed to provide a low-resistance pathway xylem. Only recently have we started gain molecular insights into these cells, which allow us probe how roots coordinate communication with environment across ba...
