AWR1642BOOST: Horizontal and vertical radar scan in synchronization using AWR1642BOOST + DCA1000EVM setup

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: DCA1000EVM,

Our Task is to capture a 3D scene inside a closed room (15~20meter length, 15~20meter width, 4meter height) from single viewpoint. For this task, we want to use “AWR1642BOOST + DCA1000EVM” setup with an RGB Camera.

Our requirements:

  1. Minimum 30 frames (scans) per second capture speed
  2. Capture vertical frame and horizontal frame simultaneously
  3. Use an RGB camera which can be triggered by DCA1000EVM, to capture RGB image of the scene such that radar scan by AWR1642BOOST and RGB image by camera are captured in synchronization.

 

Question to TI technical Team

Q1) How many radar scans per second a single “AWR1642BOOST + DCA1000EVM” setup can achieve?

Q2) Can single “AWR1642BOOST + DCA1000EVM” setup capture both vertical and horizontal frames simultaneously?

Q3) If 2 “AWR1642BOOST + DCA1000EVM” setups used, where one setup is for horizontal scanning and one setup for vertical scanning, then how to synchronize both setups? Do you provide hardware triggered sync signal or software post processing synchronization?

Q4) If 2 “AWR1642BOOST + DCA1000EVM” setups used, where one setup is for horizontal scanning and one setup for vertical scanning, then how to make sure that their carrier frequencies (76-GHz to 81-GHz) do not interfere with each other?

Q5) Can 2 “AWR1642BOOST” (one is for horizontal scanning and another for vertical scanning) + 1 “DCA1000EVM” setup capture both vertical and horizontal frames in synchronization?

Q6) Please suggest additional TI developed hardware/software if required for synchronization mentioned in above questions.

Q7) Please suggest a TI developed RGB camera for the above mentioned task

Q8) Does TI provide onboard/software based radar + camera calibration?

  • Hi,

    I recommend that you review the training "Introduction to mmWave sensing provided at this link.

    The radar does not have the notion of horizontal and vertical frame.

    The radar frame is constituted of a set of chirps as described in the training.

    Unfortunately our support team does not have experience with radar camera synchronization.

    However the mmWave sensor can be triggered with a "hardware pulse signal". Maybe this could be used in your project to trigger the camera as well.

    thank you
