Hi,

I had see your test result on Te Web.

about the test result

If I want to approch the result ( Angle(degress) 0 -> it's mean? , Detection Range Departing 56, Detection Range Approaching 48)

How can I set the evniroment, 

below is my test enviornmet ,but Detection Range Depating(m) about 45, Detection Range Approaching about 20 ,please help which is not correct...

1) IWR1642 HW: ES 2.0

2) IWR1642 FW: mmwave_industrial_toolbox_2_5_1/traffic_monitoring_16xx/...traffic_monitoring_16xx_lab.bin

3) config file: mmwave_industrial_toolbox_2_5_1/chirps/images/People+Tracking+and +Counting+Application/50m_longRangeTM

4 )My EVM was mounted at 2.25 meters,

5) tilted about 10 degrees down.

    Hi Melvin,

    Unfortunately, the amount the EVM needs to be tilted is misrepresented in this experiment. When tilting the device down 10 degrees, the center of the beam is pointed at the ground 12.7 meters in front of the device. This results in a very weak signal at 50 meters, and means you will not have good detection at that distance. If you angle down at 2.5 degrees, the beam will land at 51 meters, giving you better detection across all ranges. 

    You can consider lowering the bolded values in CFAR parameters: cfarCfg 4 4 15 16 8 6 0 63 63 0 1.  You could try cfarCfg 4 4 15 16 8 6 0 40 40 0 1

    Regards,
