Tracker implementation in Simulink

I have a Simulink model set up that includes a Tracking Scenario Reader block feeding into a JPDA tracker block. I can see that valid detections for a moving platform are being generated in the scenario and are being output by the reader block; however, these do not result in confirmed tracks being output by the JPDA block. I am using the default settings for all parameters in the tracker.

Is there a straightforward reason why this might be occurring?

Thomas, can you elaborate which sensors you have in the scenario?

Are these the IR sensor that we discussed in your previous question? Do you have more sensors?

[Thomas]

The tracking scenario has a sensing platform with a radarEmitter and a fusionRadarSensor. I am able to see that the fusionRadarSensor is detecting the target properly; however, the tracker is unable to produce a confirmed track based on these updates.

Is the JPDA block sensitive to the distance travelled between successive detections?

[Elad Kivelevitch]

If you only have angle-only detections, a JPDA block with an EKF (default) filter will only be able to track it as an angle-only track.

Can you reach out to support so that we can better understand what you're trying to do?

Thanks

Hi Elad,

One more question before opening a support ticket:

When I toggle the "Confirmed Tracks" output port of the JPDA block, I am seeing that all of the tracks being output have the IsConfirmed field set to false which seems contradictory to me. Should that port only output tracks with IsConfirmed = true?

Thanks,

Thomas
