This query filters tracks through every possible variation, in order to select and display a specific quota of tracks (within the time period and record limitations). The track pathways appear as a white line on the PPI, but multiple tracks can be multi-coloured to differentiate them. The variables are decided by the following categories:
Id: A unique identifier for each track.
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 The minimum speed value, either a maximum, minimum or equal to value. Toggle the 🛇, ≤, ≥, =, ≠, ⪥, and <> buttons to define the value.
Max. Speed: the The maximum speed value, either a maximum, minimum or equal to value. Toggle the 🛇, ≤, ≥, =, ≠, ⪥, and <> buttons to define the value.
...
a. Any Person
b. Unclassified Vehicle
c. Large Vehicle
d. Person Debris
e. Debris Animal
f. Aeroplane Drone
g. Boat Aeroplane
h. Large Vehicle Boat
i. Animal Unclassified
Travelled (m): how How far the tracks have travelled. Toggle the 🛇, ≤ ≤ and ≥ buttons to define the value.
...
Area Covered (m): how How far the track has travelled, either horizontally or vertically along the x/y-axis. Toggle the 🛇, ≤ ≤ and ≥ buttons to define the value. Whether the value is measured on the x or y-axis depends on which is the larger 'distance'. In the examples below, the Area Covered is defined first by the distance travelled along the x-axis, and second by the distance travelled up the y-axis.

For distance Travelled, it is a minimum value. The results will return tracks any value larger, any values further from zero, whether negative or positive. e.g. Travelled (m): 6 would return 7, 8, 9... and - 6 would return - 7, - 8, - 9... |

The results of a Track Query are displayed as a list in the Results Panel:
IdAnalyse:
ID: unique Unique alphanumeric identification assigned to each track.
First/Last Sighting: date Date and time of when the track record begins and ends.
Duration: track length Track length in time to the nearest second.
Seen: number Number of sightings of the track. Given the radar rotates four times a second, the number of sightings should be roughly equivalent to x4 the track duration (if the track does not coast.)
Coasts Ratio: value 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.
Classification: the The type of track.

Track Details Panel
Sightings: this This table lists every sighting of the track that makes up the track pathway. Select Show All Details to expand the table columns. Each table column title can be selected to re-arrange the order of the sightings e.g. select Range (m) to order the tracks by their Range value. If the sighting has an alarm icon, a red circle, click on the sighting to reveal the rule(s) this sighting broke. If the track has Show selected and is visible on the PPI Display, individual sightings can be selected and highlighted within the track pathway.
a. Recorded Time: the The time and date of each sighting.
ib. Speed: the The speed of that track per sighting.
iic. Course: the The direction of travel per sighting.
iiid. Range (m): distance Distance of sighting from radar.
ive. Coasting: specifies Specifies if ticked which sightings were Coasting (assumed) sightings.

Statistics: This table displays the following graphs;
a. Speed (m/s): The speed of that track per sighting.
b. Weight: The total number of cells that make up the target for each sighting.
c. Size: The surface area of the target, calculated using size in range x size in azimuth, per sighting.
d. Strength: The radar signal strength for a target, for each sighting.
These graphs can be ordered by:
Sighting:
Range: Distance of sighting from the radar. This option has a sliding scale, which will adjust the graphs accordingly.
...
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:

The Add Truth Data is applied for use with the ML Classification feature if it enabled in the Track Engine configuration. |

iv. Aeroplane
v. Boat
vi. Large Vehicle
vii. Animal
viii. Drone

b. Description: A description can be added.
c. Debris
d. First Sighting
Locate: This option will pinpoint the track on the PPI.
Export: export Export track record for posterity.
Create Exclusion: creates 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. See Exclusion Areas for further detail.
Status: change Change the status to draw specific attention to the track, and save from default track data culling.

This query searches through the Automatic Track Initiation data, 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:
Min. Sightings: the The minimum number of sightings a track is required to have been seen to be included in the query - loosely equivalent to track length.
Classification: the The type of track.
Areas: specify Specify the area(s) you wish to query. Do not specify if you wish to query all.
Colour: specify 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:
Min. Sightings: the The minimum number of sightings a track is required to have been seen to be included in the query - loosely equivalent to track length.
Classification: the The type of track.
Areas: specify Specify the area(s) you wish to query. Do not specify if you wish to query all.
Colour: specify Specify the colour the Lost tracks points appear on the PPI Display.
