Min. Sightings: The minimum number of sightings a track requires before it is recorded as a track. Toggle the 🛇, ≤ and ≥ buttons to define the value.
Min. Speed: The minimum speed value, either a maximum, minimum or equal to value. Toggle the 🛇, ≤, ≥, =, ≠, ⪥, and <> buttons to define the value.
Max. Speed: The maximum speed value, either a maximum, minimum or equal to value. Toggle the 🛇, ≤, ≥, =, ≠, ⪥, and <> buttons to define the value.
...
False Alarm Probability: This enables you to filter by one or more track classification types. Just click the false alarm probability. Toggle the 🛇, ≤ and ≥ buttons to define the value.
Classification Filter: Enables you to filter by one or more track classification types. Just click the required types to highlight them or deselect all to remove the filter. Classification options are:
...
Tag Preset: A text search forTag Presets.
Tag Presets: This will show a drop-down list with Tag Presets which have been configured in System Settings.
...

Results
The results of a Track Query are displayed as a list in the Results Panelpanel:
Select: Select the tracks you wish to focus on.
...
Coasts Ratio: Value that determines how much of the track period was classed as coasting.
Tag Preset: If a tag has been associated with the live track then it will be listed. Tag Presets
...
Show: Select the main column option for all of the tracks to appear on the PPI Display. Alternatively, select the Show option next to each track you wish to view. They will appear on the PPI Display, like this example below:
...
History: Select this icon to open the Track Details window.
StatusVideo Playback:Change Select the status to draw Play Video icon to play back the Videoloft video. This requires the Videoloft Plugin to be enabled and configured. Please refer here: /wiki/spaces/TUN/pages/2305163265.
Status: Change the status to draw specific attention to the track, and save from default track data culling.
On the top left of the Track Query Panel there are the Track Correlation: This feature searches for previous tracks that have been marked as lost, which are likely to be associated with the selected track. If the system detects such a correlated track, it will highlight it.
On the top left of the Track Query panel there are the following icons to be used with selected tracks:
...
Create Exclusion: Creates an Exclusion Area around the selected track's area covered. Unlike a normal Exclusion Area, tracks can recorded and followed through the Track Query Exclusion Area, but all alarms within the Area are suppressed. Therefore the Area is an exclusion zone for alarms. SeeExclusion Areas for further details.
Export: Export the track records for posterity.
Analyse: An option to analyse the selected tracks. If selected then the Tracks Analysis Panel panel will be displayed.
Status: Change the status to draw specific attention to the track(s), and save from default track data culling. This will open the Set System Status Panel panel.
Tracks Analysis Panel
...
This shows an analysis of all of the selected tracks:
...
ML Classified: If the ML Classification feature has been enabled in the Track Engine configuration, then this will be selected.
False Alarm Probability (%)Min: The system calculates a false alarm minimum probability score for each track.
False Alarm Probability Max: The system calculates a false alarm maximum probability score for each track.
...
At the bottom of the panel there are the following options:
OK: Closes the Track Details Panelpanel.
Clone Track: create a Playback Track from selected track.
| Note |
|---|
There is a limit to cloning Playback Tracks from track histories: only tracks with fewer than 200 sightings can be cloned. |
Add Track: Select this option to create an ML Truth Track from the recorded Track. It will open an Add Truth Data panel.
...
| Info |
|---|
The Add Truth Data is applied for use with the ML Classification feature if it enabled in the Track Engine configuration. |
Play Video: This will play the recorded video of the track. This requires the Videoloft Plugin to be enabled and configured. Please refer here: /wiki/spaces/TUN/pages/2305163265.
Locate: This option will pinpoint the track on the PPI.
| Info |
|---|
The Track Details panel has three tabs: Sightings, Statistics and Classification. |
...
Coasting: Specifies if ticked which sightings were Coasting (assumed) sightings.
Classification
This is explained in Classification Configs.
...
Statistics
...
This table displays the following graphs;
...
Range: Distance of sighting from the radar. This option has a sliding scale, which will adjust the graphs accordingly.

, which will adjust the graphs accordingly.
Classification
This is explained in Classification Configs.
| Note |
|---|
The Classification tab will not be available if the ML Classification feature is enabled in the Track Engine configuration. |
Add Truth Data
Clicking on the Add Track button will open an Add Truth Data panel.
This is used within the ML (Machine Learning) Classification feature which uses the first 10 sightings of a track in order to identify the classification of that track.
You can correct the classification of a track, and this will add to our track models which make predictions about future tracks.
Please refer to ML Classification for more information about this feature.
...
Classification: Select the correct classification for the truth data track.
...
Description: A description can be addedof the example data track must be added. For example, this could be the reclassification of the track or where it was seen.
Debris: Indicates if the truth data has come from the debris channel.
First Sighting: Sets the first sighting to be used for the truth data. This allows you to ignore the first part of the track if its not useful to be included as part of the truth data.
| Note |
|---|
We recommend using only a few good examples for the Truth Data, and a balanced number of each classification type, as having too many of one classification type can bias the system. |
ATI
This query searches through the Automatic Track Initiation data, ATI, which concerns how tracks are acquired. The results display the start point of the tracks pathways - the point at which tracks are first detected, within the time period and record limitations. The ATI points are displayed as coloured squares. The variables are decided by the following categories:
...
Colour: Specify the colour the ATI points will appear on the PPI Display.
...
This query searches through 'blind spot' data, which concerns tracks that are lost within the detection area. The results display the end point of the tracks pathways that finish before they leave the area of detection, within the time period and record limitations. The Lost points are displayed as squares. The variables are decided by the following categories:
