Be aware of the radar angle of detection. The radar will only detect objects within its field of view. The angle of detection is about 24º in horizontal direction and about 12º in vertical direction:<br>

Do not worry if your home page differs from the picture, there are some different versions and you will have the last one for sure. Congratulations!
You have successfully connected with radar. Now you can start to make measurements and learn about radar possibilities. Do not worry if your home page differs from the picture, there are some different format versions but are equivalent in features.  <br>
= Make your first measurement =
Now you can move the radar and make measurements over the wall at two different distances. For example, make a measurement with the radar at 2m distance and another measurement with the radar at 5m distance. You should get similar results as the following for 2m and 5m in order:<br>
<br>  MEASUREMENT AT 2 meters (TIME and FFT):  [[Image:WAVE 2m -T 600 NEWs.jpg]] &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;[[Image:FFT 2m -T 600 NEWsCOMPARING_RADAR_MEASUREMENTS.jpg]]  <br>  <br>
MEASUREMENT AT 5 meters (TIME and FFT):
[[Image:WAVE 5m -T 600 NEWss.jpg]]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:FFT 5m -T 600 NEWs.jpg]]<br>
 
<br>
 
<br>
It can be clearly shown how the IF radar signal increases frequency when the target gets more and more distance from the equipment. Look at the increment in periods (frequency) in the time domain signal, and the FFT peak has moved towards higher frequencies.<br>
