RADAR - ultra wide-band mono-static radar in the time domain

Radar measurement falls into one of two categories, namely frequency domain (FD or time domain (TD).  The main difference is that FD radar can measure very far (kilometers)  but not within millimeter accuracy, where as TD radar does not measure that far ( less than 500 meter) but within millimeter accuracy. 

In the video below a TD radar distance measurement example is shown.  The BLACK blocks indicates no object was detected, the spectrum colors indicates detection's.  Each vertical line indicate distance, starting with 1382 mm on the left and then increasing with 4.6 mm increments for each successive vertical line to the right.  

To implement radar technology successfully it is important to build filters into the software, which must be able to distinguish between the reflection of an actual object and the reflection of 'noise'.  Also you want to be able to detect signal strength and signal stability to name a few more things. 

Typical uses for this radar solution is to track both moving and static objects, within millimeters, be it in bright sunlight, darkness, dust, mist, smoke etc. environments.

The software was written in Windows C# on the UWP (Universal Windows Platform) platform.  This has the advantage that it can  be implemented on a range of devices be it a smart phone, Raspberry Pi, laptop or desktop.  Further more, we can send and receive radar data via our Windows based IoT cloud solution as well
