Compiler/IWR6843: The distance about IWR6843

Hi Hao,

What distance are you referring to? 

Please read this app note for more information on chirp parameters.

HI Chloe 

We test the people counting in a meeting room(6 meters by 4 meters)  by demo board and our board.

We use the same software and firmware. 

The demo board can test people more than 4 meters . but our board can not test may be 2 meters.

if we lower the CFAR threshold , our board can also reach at 4 meters.

we also tune the angle of our board but can not get a better result.

So we think the ability of detection of our board is lower than Ti demo board.

But when we test the EIRP of our board and demo board, it's almost the same. 

So i doubt that Does any chip pins status will affect the detection? 

Thanks 

Hi Hao?

Are you using the IWR6843ISK or IWR6843ODS board? For this demo you should be using the ISK.  Also, are you sending the same chirp as the demo?

Hi Chloe

i use the IWR6843ODS. and the chirp parameters is the same as demo board. 

we are testing the ADC raw data to check this problem

Thanks
