IWR1642BOOST: High_Accuracy_Visualizer 1.2.0

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1443, IWR1642, , IWR1443BOOST

Hello!

I am experimenting with IWR1642, IWR1443

The figure below is a screenshot of the screen displayed in High_Accuracy_Visualizer 1.2.0.

- IWR1642BOOST

- IWR1443BOOST

I am testing the level_sensing of mmwave_industrial_toolbox_4_6_0.

--------------------------------------------------------------------------------------------------------------------------------

IWR1642BOOST's RangeLimitCfg was changed.

However, there is no change in the FFT graph displayed in the Range Profile.

IWR1443BOOST's RangeLimitCfg was changed.


The FFT graph displayed in the Range Profile changes the min range according to the value defined in high_accuracy_demo_14xx.cfg.

High_Accuracy_Visualizer 1.2.0. Please let me know if it displays differently.

--------------------------------------------------------------------------------------------------------------------------------

--------------------------------------------------------------------------------------------------------------------------------

What is the meaning of RangeLimitCfg 2 1 1.0 3.0 in the contents of high_accuracy_demo_16xx.cfg?

RangeLimitCfg

2 : ???

1 : ???

1.0 : min range

3.0 : max range

--------------------------------------------------------------------------------------------------------------------------------

thanks

    Hi Lee

    The Range Limit Cfg feature in the 16xx and 68xx versions of the lab simply specify the zone of interest to perform the zoom FFT.

    The 14xx and 64xx versions of the lab actually remove bins outsize the zone of interest for the 1D FFT.
