Sensor Surveillance Fence

The Sensor Surveillance Fence Plugin is a component of the KeepTrack application that allows users to visualize a surveillance fence for selected sensors. This plugin enhances the space situational awareness capabilities of the application by providing a visual representation of a sensor’s surveillance area.

A surveillance fence is a region of space that a sensor is likely to scan or monitor. By visualizing this area, users can better understand the coverage and capabilities of the selected sensor. Sensor’s can’t look everywhere at once, so the fence represents the area where the sensor is most likely to detect objects.

Tip

Some sensors are volumenetric, meaning they continuously scan a 3D area. These sensors will show a 3D volume even when surviellaance fence is enabled.

Features

• Toggle surveillance fence visualization for selected sensors
• Integration with other sensor-related plugins
• Responsive to sensor selection and deselection events

User Interface

The plugin adds the following UI element:

1. A “Sensor Fence” icon in the bottom menu for quick access

Note

The icon is initially disabled and only becomes active when a sensor is selected.

Usage

Enabling Surveillance Fence View

1. Select a sensor using the Sensor List Plugin
2. Click the “Sensor Fence” icon in the bottom menu
3. The visualization will update to display the surveillance fence for the selected sensor

Disabling Surveillance Fence View

1. Click the “Sensor Fence” icon again to disable the visualization

Note

The Sensor Surveillance Fence view is mutually exclusive with the Sensor FOV view. Enabling one will automatically disable the other.

Integration with KeepTrack

The Sensor Surveillance Fence Plugin integrates with several KeepTrack components:

• SensorFov Plugin: Coordinates with this plugin to ensure only one view (FOV or Fence) is active at a time
• Event System: Responds to sensor selection and deselection events

Caution

There are some edge cases where the icon might remain available when it should be disabled. While this doesn’t break functionality, it’s a known issue that may be addressed in future updates.

Development

When extending or modifying the Sensor Surveillance Fence Plugin, consider the following:

• The plugin follows the KeepTrackPlugin architecture
• It registers event handlers for sensor selection and deselection
• The enableSurvView_ and disableSurvView methods control the visualization state

Code Configuration

The plugin supports the following configuration options:

• bottomIconCallback: Function called when the bottom icon is clicked
• isRequireSensorSelected: Set to true, requiring a sensor to be selected for the plugin to function

Troubleshooting

• If the “Sensor Fence” icon remains disabled after selecting a sensor, check if the sensor selection event is being properly triggered
• Ensure that the required dependencies (e.g., SensorFov plugin) are properly initialized
