AWR2944EVM: Received Signal

Dhiraj Sangwan

Part Number: AWR2944EVM
Other Parts Discussed in Thread: DCA1000EVM

Tool/software:

in AWR2944evm there we have a 4Tx and 4Rx. Each receiver (Rx) receives a reflected signal, so we have four different received signals. And at the output, we have only one received signal.

Then, how can an AWR2944EVM be able to produce a single received signal?

Does it perform any processing techniques like the Beamforming technique over the received signal or some other processing is being done on the board, please specify.

Hello Samhitha,

I read that module, but this module does not tell about the signal received from multiple receivers. It tells about the multiple received signals on one receiver and its graph along with the transmitted chirp.

I connected the AWR2944EVM to the DCA1000EVM for the collection of raw data, and I got a '.bin' file of the raw ADC data. When I did further processing, I distinguished the data according to 4 Rx and got the four graphs of the received raw data.

When we performed the same thing on mmWave Demo Visualizer with the same setup and downloaded the '.dat' file and then after processing that '.dat' file on MATLAB, I got only 1 graph i.e. range profile graph.

I just want to know what processing is being done on these raw data or graphs to get the one-defined output or graph (like range profile) we get on the demo visualizer/MATLAB.

Regards,

Dhiraj

Hi Dhiraj,

You can refer to the SDK demo (C:\ti\mmwave_mcuplus_sdk_04_06_01_02\mmwave_mcuplus_sdk_04_06_01_02\ti\demo\awr294x\mmw) and understand the processing chain.

You can find the documentation at - "C:\ti\mmwave_mcuplus_sdk_04_06_01_02\mmwave_mcuplus_sdk_04_06_01_02\ti\demo\awr294x\mmw\docs\doxygen\html\index.html"

Samhitha
