IWR1443BOOST: question about duplicate reflections from certain material surface in range profile and point cloud

Part Number: IWR1443BOOST

we are using 3d point cloud from 1443 board to plot mapping of our surroundings,and for most of object like wall it plot correctly. but from our observation, for objects like glass and metal door, it appears multiple layers behind the main object graph, [ show in graph below]

this is the actual testing environment:

Since in the real testing environment there is no other object behind the tested glass door, we want to know what cause for this.

besides, we also plot range profile to see if there are detected reflections behind the main object:

as shown above, we the radar get close to the object,  there are small peaks showing behind the main peak.

  • Hi,

    It is quite common to see like double reflections or multipath reflections.   Basically, the reflected signal can be bounds back by the EVM board or setup tables.   You can try to shield the EVM board (and setup tables and etc) other than the antenna area to see whether this behavior will be reduced.  

    Best,
