The next step in building the drone tracking is to set up the Sweep Bands. Click Configuration Settings A window appears on the screen to configure the tracking bands as shown in Figure: Configure Tracking Bands. The band settings at 2.4 GHz ISM Band and 5 GHz ISM Band are standard drone control settings. The first two windows (2.4 GHz ISM Band and 5 GHz ISM Band) default with the standard settings.

Sweep Band Configuration
Restore Default:
Click to restore default values for band 1 and band 2.
Set up Sweeps
The first two windows that are not labeled “Custom” are set to the default values shown. These are standard drone control settings.
Start Frequency
The start frequency of the monitored band.
Stop Frequency
The stop frequency of the monitored band.
Reference Level
Reference level for the monitored band.
RBW
reference level for the monitored band.
Antenna Port
Antenna port for the monitored band
Mask Offset (dB)
mask offset for the monitored band.
Min Width (MHz)
The user can set the Minimum Width for mask violations. Independent for each band and can be changed for the drone detection application. As a cautionary indicator, the spin button background displays a red or yellow color to indicate the setting status. See Minimum Width Settings.
Custom 1 through Custom 3
Check boxes for additional band settings. When in Monitor mode, these are the frequency bands that will be monitored for drone activity.
Events
Transient Filter
Requires a mask violation to persist before tracking starts. Use the transient filter radio buttons to set to Low or High. Low requires three consecutive mask violations before tracking starts. High requires five consecutive mask violations before tracking starts.
Record stationary events
Keep stationary events in tracking event log
Monitor
Monitoring Mode
The monitoring mode list consists of On Demand, Monitor Only, Monitor and Notify, and Monitor and Track. For demonstration purposes, Monitor and Track should be selected. Other options are present when the system integrator is using multiple sensors for detection and tracking (such as the use of cameras or radar).
• On Demand: An idle state where AeroShield is running, but no RSM communication is active.
• Monitor Only: Used for setup, configuration, and performance checking. Only mask violations are shown on the screen. There are no notifications and tracking performed.
• Monitor and Notify: Monitors for mask violations and will notify a user if there is a mask violation. Notification have to be configured; through the API or via email.
• Monitor and Track: Normal mode of operation.
Mask Accumulation Time:
Set the accumulation time to:
• Low: 2 second max hold capture time used to create masks with 5 dB Mask Offset automatically set for each band.
• Medium: 5 second capture time with a 4 dB Mask Offset.
• High: 14 seconds time with a 3 dB Mask Offset.
• Very High: 29 seconds time with a 2 dB Mask Offset.
Enable Adaptive Masks
Uses trace data from monitoring sweeps to update the mask periodically. AeroShield will use the monitoring scans to periodically update the mask. This allows for signals that were in the background when the mask was taken to dissipate over time if it goes away. However, if the signal comes back, it will trigger a violation.
Report Options
Always generate reports:
Every time a single tracking event occurs, it is logged in the tracking report. A single tracking event is initiated at the start of a mask violation and ends when the correlation is no longer detectable. A report can be viewed as discussed in Open a Tracking Event Report.
Automatically open reports:
Automatically opens tracking reports when created. AeroShield will use the monitoring scans to periodically update the mask. This allows for signals that were in the background when the mask was taken to dissipate over time if it goes away. However, if the signal comes back, it will trigger a violation.
Mail Server Configuration
Email event reports:
Check generates an email after a report is generated. To have emails sent, complete the Address field, Host name field, and Port Number. If User Authorization is necessary, complete the User Name and Password fields.
Click Save and then click Close to close out the configuration dialog.
Note
Most cell phone service providers should allow text messages through email. The setup may be selective for each carrier. A drone incursion typically lasts less than 20 minutes, as that is the average battery charge. Typically, text messages are much faster than email. This is a feature of the phone service, rather than a feature of the AeroShield API Software API software.
Note
Editing any of the RSM band frequencies in the Configure Tracking Bands dialog may require the Mask to be regenerated.
Minimum Width Settings
The Configuration Tracking “Min.Width” settings can be set for mask violations.
Color Coded
A color cautionary display fills the Min. Width field if set too low or too high. See Figure: Min. Width Color Code.
Yellow: If this value is set too low, it affects the spatial resolution of the TDOA measurement.
Red: If the value is set too high, the Min. Width field turns red.
Min. Width Color Code
Event Log Color Indicators
The Event Log also displays the colors as described above when the Min. Width settings are too high or too low.
Green: Indicates tracking started. The User can scroll back and find the starting point of a given track. See Figure: Event Log Color.
