IWR1843BOOST: Range profile and noise profile waveforms

user244678

Part Number: IWR1843BOOST

Tool/software:

Hi,

In the range profile and noise profile of the mmwave demo visualizer, is the decrease in level of the bins on the high frequency side due to the LPF?

If it is caused by the LPF, is the cutoff frequency of the LPF automatically selected according to the chirp setting?

Best Regards,

Additional information.

The firmware is mmwave_sdk_03_06_01_00-LTS demo.

And the version of mmwave demo visualizer is v3.6.0.

Hiroyuki

Hi Hiroyuki,

Yes, it is because of the LPF used which is limited to 90% of the Nyquist band for the selected configuration

You can check the configuration and range calculation at the TI Sensing estimator

Hi Abhishek,

Thank you. Is this LPF digital?

I would like to know the characteristics of the filter.

This LPF is in analog. It is internal to the device. We cannot provide the characteristics of this filter
