IWR1443BOOST: DCA1000EMV evaluation board with continuous response over time

Jonathan Navor

Part Number: IWR1443BOOST

Hi Guys,

Good day. Could you help us on our customer's concern below.

I have copied here the whole details in behalf of our customer:

I am using the IWR1443BOOST sensor and the DCA1000EMV evaluation board.
The problem I encounter is that when I view the sensor response graphs they are like images of a single instant in which they worked. While I should be able to use the sensor to get an answer in real time.
I'll give a very simple example to help you understand:
I would like that if I put my hand near the sensor and then move it away, this is able to give an answer in real time, in which I can first see an approaching target and then move away.
While I can only get an instant response of when I hit play, and the graph shows me the position of the hand only in the instant in which I decide to view the response of the sensor.
I would like to know if it is possible to have a continuous response over time, and what I have to do or what settings I have to set to have this functioning.

Thank you in advance for the support.


Best regards,
Jonathan

    Hello

    The mmwave Studio + DCA1000 combination allows users to

    1.) capture  raw sensor data and save one shot multiple frame of data  to the host computer (Bin/dat format files)

    2) mmwave studio's matlab utilities post process the saved data to show various plots

    Data plots per frame are available by browsing the plots/gui interface.

    So essentially user's should not expect real time response for this tools output.  This tool is intended for Offline algorithm development with the saved data in step#1 or quick analysis of results with simple post processing provided in the tool.

    In order to see real time response user can try :

    1) Out of box demo  provided via SDK or Tirex offerings - please see Industrial tool box under dev.ti.com

    2) Application specific demo provided in Tirex tool box.  Please see ti.com/iwr applications  page.

    Thank you,

    Hi Vaibhav,

    Thank you for your answer. Here is the next question. 

    Our customer asked if there is any method to have a sensor sampling that lasts at least ten seconds?

    They notice that changing the settings they were only able to get a sample for just over a second.

    Is there some settings to change to have a sampling of 10 seconds or it is not possible through the iwr1443boost sensor and the dca1000emv card?

    Thank you in advance for the support. 

    Best regards,

    HI, there:

    You can program the frameConfig in radar studio to cover 10 second.  For example, if the frame duration is 50ms, then you can program the number of frame to be 200 to cover 10s.   

    Best,
