AWR2944EVM: Calculation of Chirp for AWR2944 DDM mode

Part Number: AWR2944EVM
Other Parts Discussed in Thread: AWR2944

Tool/software:

Hi,

I am working with AWR2944 evm board in DDM mode and I want to use the radar in a specific case.

Is there any tool which I could use to calculate the chirp based on Max Range, Range Resolution, Max Velocity and Velocity Resolution ?

for the TDM mode I used mmWave_Demo_Visualizer for chirp calculation but i didn't find a way for DDM mode.

Thanks.

Currently we do not have such tool to get the required configuration from the given parameters. You can refer to Programming Chirp Parameters in TI Radar Devices (Rev. A) to configure the chirp parameters based on your requirement.

Hi Mohamed,

Please refer to Programming Chirp Parameters in TI Radar Devices (Rev. A). You can also watch the videos on mmWave radar sensors | TI.com. To understand about each parameter of the command in the configuration file, you can refer to "C:\ti\mmwave_mcuplus_sdk_04_06_01_02\mmwave_mcuplus_sdk_04_06_01_02\docs\mmwave_mcuplus_sdk_user_guide.pdf".

Hi,

I already checked the documentation but I need a tool or a script to calculate the chirp in DDM mode for a specific scenario.

Thanks.

Hi Mohamed,

As mentioned in my previous reply, currently we do not have such tool.
