Hello @htl ,
Unfortunately, the DW3000 is only capable of transmitting or receiving (but not both) at a given time. Therefore, to experiment with radar, you would need to use 2 DW3000 devices.
Here is a research paper where 2x DW3000 devices were used: UWB Bistatic Radar Sensor: Across Channels Evaluation | IEEE Journals & Magazine | IEEE Xplore
We also have a future product more targeted for radar. Please see the the note from @Yves_Bernard_Qorvo here: Using your product for UWB sensing ( like radar) - #2 by Yves_Bernard_Qorvo
