== Security ==

Security is one of the field applications of radar technology. IGEP RADAR LAMBDA has been used for these purposes, we want to show you here some of the results:.<br>

Measurements of a person approaching the radar by walking slowly were made during 7 seconds, capturing 1.000 measurement files.

The modulation used was: -T 1600

The 1.000 measurement files were captured and processed with matlab. FFT was made for each measurement obtaining the next 2D plot:

[[Image:SECURITYs.jpg]]Y axis represents twice the distance<br>

X axis represents the measurement

it can be shown that the person is detected from 18m in the first measurements moving to 15m in the last measurements. <br>

The next is a 3D plot of the same data, where Z axis is the FFT module level:<br>

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

    [[Image:SECURITY-Bs20m 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 with if you are interested on a development for an specific application need.jpg]]
