AWR1642BOOST: Time to form a tracker

Shraavan nnv

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642

We use AWR1642 with USRR/SRR profile, we are only processing only trackers(TLV 3) in the code.

Test Scenario : A vehicles enters the FOV of radar at a range of 2 metres with a velocity of 20 kmph. Tracker is formed at approximately 9 metres

Observation : Approximately it is taking around 1 sec to form a tracker .

Is our observation accurate? Is there a way to reduce this parameter ..

Hello Shraavan,

How have you profiled this data? is it just through the GUI observation?

Our query is not based on GUI observation , we have profiled the data .

Shraavan,

What is your benchmark requirement to form the tracker?

If we could reduce it to 500 ms (half of current time ) , it would be good . The reason is sometimes if the vehicle is moving at higher speeds, it is taking approximately more than 15 meters to form a tracker from the time cluster is formed.

Could you guide us also more relevant parameters(Kalman filter, tracking decision.... etc)to improve the tracker formation time .

Hello Shraavan,

Below code in the dss_data_path.c waits for filling up the tracker data.
if (trackerState[ik].tick < MIN_TICK_FOR_TX)
{
continue;
}

The "MIN_TICK_FOR_TX = 10" by default which means you are waiting for 600ms(60ms frame) for creating the tracker output.

You can reduce this value to "MIN_TICK_FOR_TX = 5" and reduce this time to form the tracker output.
