AWR1843BOOST: AWR1843BOOST:No noticeable change in phase of Inhale and Breathing in Occupancy and Vital Signs: Automotive toolbox

Hello

Note on mmWave demo examples:

mmWave demo examples are intended to show the capabilities of TI's mmWave devices.  These demos use mmWave radar data  processing and algorithm techniques which are available publicly.   As such the GUI, plots, processing examples are provided 'as is' for demonstration purpose.   We may be able to guide you further with device specific details but the details of algorithm  implementation, customization routes and addressing specific corner cases are outside the scope of E2E forum support.  

We encourage users to extract the mmwave data  from device and implement their own algorithm on the programmable cores available on the (applicable) devices.

Having said that  allow us to address the questions you have:

Sorry about the delay in addressing this query, however  responses were sent in  newer threads - lets go over each of these.

1- Why there is no noticeable change in phase of Inhale and Breathing in Occupancy and Vital Signs

 Please help us understand  which of the two is the appropriate question:

1.A ) the demo doesn't work  -->  No difference in  heart rate/breathing rate  between occupied vs unoccupied vehicle/detection position.

or

1.B) Demo is unable to detect the difference  in heart rate  vs breathing rate  when position is occupied by person.

We have provided/referenced development documents from the Tirex/labs which show the details of implementation and how the  detection rates are related to displacement.

Reference :  Slide #4

2- AWR1843BOOST: Occupancy Detection and Vital Signs: Repeated Question

Apart from repeat in the question  addition questions asked here:

Specific questions about implementation difference were addressed.   Hope nothing else is open here.   Please let us know if any of the suggestions in the above thread do not address your concerns  considering the intent of the demo.

Thank you,
