​
Covert Spectrum Monitoring
​
Some environments are very harsh, to install a permanent structure for RF monitoring, like:
-
Hostile locations: contested borders, war zone, & terrorist zone.
-
Environmental challenges: cliffs, forests, swamps or dunes.
-
Rapid deployments: Detecting jamming, & Drones used in smuggling drugs, & weapons into prisons & borders.
-
Emergency: VIP visit, Sporting event.

​
Maritime Safety & Security
​
-
Sea border security responsibilities
-
Responding to vessels with problems
-
Collisions
-
Medical incidents at sea
-
Pollution control
Interference, due to:
-
Channels allocation unrespectable.
-
Uninformed users or foreign nationals
-
Intended interference on Mayday calls.
-
Carelessness
​
Border Monitoring
​
-
International borders can cover hundreds or even thousands of miles.
-
Impossible to secure every square mile of a border with a physical manned presence
-
A network of high-performance RFeye receivers can pick up RF spectrum transmissions.
-
A cell phone, VHF radio or other device can be detected, classified, & geolocated.
-

​
Regulatory
​
-
Managing the spectrum in more effective, & efficient way by Regulators.
-
EM spectrum is very valuable resource.
-
Used in: making phone calls, watching television, GPS navigation, & etc.
-
National regulators need to ensure, that the spectrum is uncongested & interference free.
-
As the number of “connected” devices increase, the pressure on the RF spectrum increasing, which increase the need of innovative ways to monitor and manage the spectrum.
​
Hybrid Geolocation
​
-
When it comes to geolocation performance, you don’t need to compromise.
-
AOA/TDOA are used for geolocation over wide areas.
-

​
DF in urban environments
​
-
Direction Finding (DF) systems can often seem to fail, when used in the urban environment.
-
This problem can be attributed to multipath propagation.
-
Using the multiple Lines of Bearing (LOB) obtained as a single vehicle-mounted DF antenna array moves, to avoid multipath.
-

Airport Interference
​
-
Communications, navigation systems and even Autoland systems can be impacted by RF interference at airports.
-
Preventing and quickly resolving interference at airports is essential for avoiding disruption, financial loss and serious accidents.
-
Engineers may be sent out to an airport over ten times with an portable RF monitoring and each time find that the interference source has been and gone.
-
Continuous RF monitoring solution isn’t only effective, but also cost effective.

​
Electro-Optical Integration
​
-
Optical systems extend our own senses using superior optics and image enhancement.
-
They are able to identify and track drones based on their visual signature, and, when using infrared (IR), by a drone’s heat signature.
-
Optical systems give an unrivaled understanding of context. For example, by verifying if a drone is weaponized.
-
They do, however, still need additional hardware to perform geolocations and can encounter difficulty in coping with bad weather and bright sunlight.
-

Acoustic Sensors Integration
​
-
Acoustic sensors are programmed to recognize the unique sounds produced by drone motors.
-
They rely on a library of sounds from known drones, so if a drone isn’t in the library, it won’t be detected.
-
Range from the target, background noise and strong winds can also influence the effectiveness of acoustic sensors.
