IWR1642: close detection of trafficMonitor

Part Number: IWR1642

Hi Technical Support

I tried the following demo, but it seems to be difficult to detect near the radar (within 10m).

C:\ti\mmwave_industrial_toolbox_3_6_2\labs\lab0013_traffic_monitoring_16xx\gui\tm_demo.m

Is there a process that is not detected near the radar?

Dear Amanda

Thank you for reply.

And, thank you for telling me about related threads.

But, It is hard to see within 10m even in a car with a large RCS instead of a hand.

Sorry, is there any detailed information about the following?

> 1. The range resolution of the MIMO configuration is only 0.25m. In the processing chain, the first few range bins are discarded from detection due to FFT leakage.

Hi User,

We are still looking into this.

Hello,

The DC calibration function is detailed in the doxygen of the mmWave SDK documentation. The first few range bins are affected by FFT leakage. I would recommend to evaluate close distances by using the Out of Box demo instead of the traffic monitoring demo. In addition, the latest TM demo using 6843 or 1843 are recommended for compatibility with the latest SDK. Please consider using this demo instead if you need more customization for short ranges.
