IWR1642BOOST: retrieving and analyzing the data

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642, MMWAVE-SDK, IWR6843, IWR1443

Hello.  I am a newbie and I need some insights regarding the board or similar controllers. 

I am trying to detect a 2 mm metal object taped to a paper 20 cm away from the board. I ran the high accuracy lab and the board is working and managed to get the code compiled. however it can only detect big objects even if I narrow the range. so far unsuccessful. 

How do people use the code if I want to modify its characteristics? is that even possible?  I can't tell what algorithm is used to detect objects and how mapping objects is done as shown in Ti videos. 

TLDR: I want to narrow the range, increase the resolution of the IWR1642 board to tell 3 mm or less sized objects apart from a distance of 20 cm or less. 

Any advice is greatly appreciated. Thank you

    Hi Mohammed

    Can you discuss your application in more detail?

    You will want to continue development using the mmWave-SDK, though more likely you'll want to use the IWR6843 or IWR1443 device and corresponding EVMs.

    Thank you for answer Akash

    I have both the IWR1443 and IWR1642.  I am able to compile the majority of the labs.  I want to know how I can edit the labs/ mmWave-SDK codes to change the controller's range, accuracy, number of working antennas, and output the data received from the EVM to Matlab or Excel file.

    Hello

    In order to get started with sensing and observing the result of object in the mmWave view, the demss come  with tuning option.

    Modifying - compiling  are good steps to do after you have observed how the results of existing demos fair for your use case.

    As such for the object you mentioned, have you been able to look at the point cloud results int eh OOB demo + mmWave visualzier (this is provided in the TIrex)

    It would also help us know which video were you referring to.

    Thank you
