IWR6843ISK: IWR6843 overhead people counting config file

Thanks, but I really have a lot of ghosts... that I'm not able to eliminate

Some more detailed questions:

SceneryParam -3 3 -3 3.0 0 3 - There are 2 more values, are they z limit values?

GatingParam 10 3 3 3 0 - There are 5 parameters , what do they represent?

AllocationParam 50 120 0.01 20 1 15 - the third one is (I suppose it is the radial velocity but in x-y plane or xyz? can I set it to zero?

VariationParam 0.2887 0.2887 1 1 - I have a lot (really a lot of ghosts), do these parameters affect the ghosting elimination?

MaxAcceleration 1 1 1 - What these parameters mean?

AllocZone 0 1 - What these parameters mean?

CloudPersistence 0 - What these parameters mean?

SNRFilter 4 40 - What these parameters mean?

Last question:

What's the cartesian reference system of the radar, i mean the Z axis is the axis perpendicular to the plane of the radar?

Thanks

Hi Alessandro,

First, to answer your questions:

SceneryParams <X Left> <X Right> <Y Close> <Y Far> <Z bottom> <Z Top>

Gating Param <Volume> <X Limit> <Y Limit> <Z Limit> <Doppler Limit>

AllocationParam <SNR Thresh> <SNR Obscured Thresh> <Min Radial Velocity for allocation> <Points Thresh> <Max distance for clustering> <Max doppler difference for clustering>

SNRFilter - <Max Range to Filter> <Filter Points below this SNR>: SNR Filter allows you to set a low CFAR threshold to extend the range of the demo, while ignoring low SNR noise close to the device. SNRFilter 4 40 requires all points within 4 meters of the device to have an SNR of at least 40 if they are to get passed to the tracker.

The rest of the commands are now set automatically, and will be deprecated.

For the coordinate system, assume you are looking at the device, with the antennas at the top and power at the bottom:

• X is right and left along the plane made by the antenna face
• Y is into and out of the antenna plane
• Z is up and down along the antenna plane

My recommendation for reducing ghosts is to increase allocation thresholds.  Ensure the gating parameters are large enough to associate all points near a target with that target.

Thanks for the reply!

Now understood I've a few problems with the config file, in particular with AllocZone 0 1; CloudPersistence 0; SNRFilter 4 40 parameters.

It seems that it doesn't recognize them.

In this way I can not adjust the SNRFilter and I have a lot of ghosts.

I attach the output.
