AWR1843BOOST: Doubts while parsing the data

Hi Tanoop,

Which application are you using on the AWR1843? Is it the OOB demo or some TI-REX application?

I am trying to track objects for my Collision Avoidance System

Hi Tanoop,

I am going to assume that your are using the MRR example as a base for your application. You can find the details of UART TLV here.

{radar_toolbox_<ver>}/source/ti/examples/ADAS/medium_range_radar/docs/Medium_Range_Radar_users_guide.html

This should provide you with the info you need.

Regards,

Kaushik

I have gone through that documentation, but it has not mentioned my main doubt that 

Q)As I understand detected objects are all the reflections of the radar and the tracked objects are the objects relevant to our application .so tracked objects are always a subset of detected object but sometime I am getting the number of tracked objects is greater than detected objects....how is this possible

like this

like here where no. of tracked objects is greater than no. of detected objects..

Hi Tanoop,

There is no necessity for the tracked objects to be a subset of the detected objects. The tracked object list is both a function of current frame's detection list and detections from the previous frame. 

That being said, it is highly unlikely that you end up with more tracked outputs than actual list of detections. Can you share some screenshots across frames that describe this behavior so that the same can be looked at in detail?

Also, can you mention any changes you might have done on the example or the configuration?
