IWR1642BOOST: When to use the DCA1000

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642

Hi,

I am a bit confused about the DCA1000 and the IWR1642. It looks like we can use the IWR1642 alone with the mmwave SDK to get the data from the device and the DCA1000 also allows us to get the data from the IWR1642. What is the advantage of using the DCA 1000?

    Hello,

    Yes, the Iout of box mmWave SDK demo does enable capture and logging of data. This data is processed data ie point cloud or range-doppler heatmap. 

    For users who want to develop their own processing algorithm the DCA1000 is used to capture the raw ADC data. Then the user can then iterate offline different processing algorithms. The advantage here is that with raw ADC various algorithms can be applied to the capture data to evaluate the advantages/disadvantages offline. Of course for it to be most useful you would need to be prepared to develop your own data processing scripts.

    Thanks for the reply. Also I see that the IWR1642 does some interference mitigation preprocessing on the ADC data. Is it possible to get this preprocessed data or is there a public script for this preprocessing?

    Hello Kalvik,

    Can you clarify your request? There is chirp quality data that can be received. The source code for determination of the CQ data is not public.

    I was asking for a script to get CQ data. But, yeah nevermind. Thanks.
