AWR1843BOOST: object detection with EVM is not proper, getting wrong object detected points

Part Number: AWR1843BOOST

Hi,

Thanks!

Doing basic testing of EVM, keeping module close to the wall & its throwing 91 objects detected. Module is very close to wall. Same output getting in demo visualizer tool also. PFA image.

Is it a right way of testing module?

Can you please confirm minimum size of object required for detection? Here is the header info which I received:

0x02, 0x01, 0x04, 0x03, 0x06, 0x05, 0x08, 0x07,
0x02, 0x01, 0x02, 0x03,
0x60, 0x07, 0x00, 0x00,
0x43, 0x18, 0x0A, 0x00,
0x0B, 0x00, 0x00, 0x00,
0x79, 0x10, 0x5C, 0x29,

    Hi,

    By placing the sensor close to a wall you will get multi-path reflections.

    No, this is not the right way of testing the module.

    Usually, first we test the sensor with a corner reflector in some open wide space so that there are no additional reflections.

    Thank you
