DCA1000EVM: DCA1000 captured data analysis

Ti_HugeSunfish

Part Number: DCA1000EVM
Other Parts Discussed in Thread: AWR1642

I used AWR1642 with DCA1000 to capture the raw data and analyze on Matlab.

I used function "cumsum" to get the time domain data. But the result (figure1) is different from figure2 generated by mmWave studio.

I just plot only one chirp, one frame, one channel in the graph.

Can someone tell me what's going on? Thanks a lot!

Hello,
I assume you are capturing the data using mmwave studio. Are you processing the same capture file that mmwave studio used in the post processing? The default file name set in the mmwave studio is adc_data.bin.
The data format in this file is available in the mmwave studio users guide : software-dl.ti.com/.../mmwave_studio_user_guide.pdf . Could you confirm your assumption of the data match it?

Regards,
Vivek
