-w write ===> and save the captured data into text files

<br> The 1.000 measurement files were captured with the radar and processed later with matlabon a PC.  FFT was made for each measurement obtaining the next 2D plotwith matlab:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:SECURITYs.jpg]]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:SECURITY-Bs.jpg]]

It can be clearly shown that the person can be clearly tracked over the signal noise level (blue color).

20m range can be acceptable in most security systems but it is possible to apply CFAR processing techniques in order to increase the range over 100m. In addition, some more directive antennas could be developed to improve this parameter. Please contact [mailto:radar@iseebcn.com radar support] if you are interested on a development for an specific application.
