RADARduino Update – Testing Partially Populated PCBs

As a partially built kit, the RADARduino boards need to be tested before being packaged and sent to customers to verify that the assembly of the RF section is successful and meets specifications.

Contains an RF power meter, Doppler simulator

Contains an RF power meter, Doppler simulator, a host computer (Raspberry Pi), and interface to an external oscilloscope for measuring system performance.

I have built a special piece of test equipment that in conjunction with a test fixture will allow for testing of transmitted output power and receiver functionality.  The box is still under construction and will eventually interface with an external oscilloscope and contain a built-in RF power meter.  This box replaces several pieces of costly test equipment with common off-the-shelf RF components.

Holds the PCB in place while pogo pins and fuzz buttons make electrical contacts to pertinent traces and pads.

Over the next couple weeks as I finish this box, I will test the new prototype boards and verify the clamshell fixture as well as the test box functionality.

  1. Very nice project,

    which is the maximum detection distance for a walking person?
    Did you compared the arduino performance with MIT can radars?
