Why use a scanner?

A passive scanner approach
to radarless drone detection

Focus Retina detects drone communication signals without transmitting radar waves,
reducing system exposure while supporting EO/IR, radar options, and hybrid sensor integration.

01
Passive Detection
Unlike active radars that expose their position to adversaries, our scanners detect drones by simply receiving signals. This passive approach ensures a completely covert operation, protecting the system's location from enemy detection and electronic tracking.
02
Zero Electromagnetic Interference (EMI) to Surrounding Facilities
Since the system does not use radars or active sensors, it emits no radio frequencies. This ensures completely interference-free operation with neighboring equipment and EMI-sensitive facilities.
03
Lower Initial
Deployment Costs
Without relying on high-cost radar equipment, facilities can reduce initial investment costs and simplify deployment, especially when existing EO/IR camera assets can be reused.
04
Regulatory Freedom and Hassle-Free Licensing
Because the system operates as a purely passive receiver without transmitting any active radio frequencies, it is entirely free from complex spectrum regulations, frequency allocation issues, or restrictive government licensing requirements. This allows for immediate deployment across any jurisdiction.
05
Versatile Multi-Sensor Integration
While Focus Retina operates primarily as a cost-effective passive scanner, it features a highly adaptable architecture. To meet diverse operational needs, the system seamlessly integrates with various hardware, including legacy radar options, RF-based configurations, and hybrid sensor arrays.
Scanner vs Radar

Complementary technologies for
smarter airspace security

While radar excels at tracking physical objects, passive RF scanning provides a critical, covert layer of
defense by capturing communication signals without expanding your system's exposure.
Together, they solve distinct operational challenges based on your facility's threat scenarios.

Scanner
Radar
Detection Method
Passive detection based on drone-controller communication signals.
Active detection based on transmitted waves and reflected signals.
System Exposure
Does not transmit radar waves, helping reduce system exposure.
Transmits radio waves, which may expose system location in sensitive environments.
Deployment Cost
Can reduce initial investment costs, especially when existing EO/IR camera assets are reused.
Typically requires higher equipment and integration costs.
Regulatory ‍
& Licensing
Entirely free from spectrum regulations or government licensing, allowing for immediate installation and deployment.
Requires complex frequency allocation, transmission licenses, and strict regulatory approvals prior to deployment.
RF-silent drones
Limited when drones operate without
detectable RF communication signals.
Can detect flying objects regardless of communication signal emission.
Controller Awareness
Can detect and locate the drone
controller(pilot).
Cannot detect or locate the controller;
only detects the airborne object.
Mobile Operation
Small and lightweight antenna structure
supports OTM and vehicle-mounted
applications.
May be limited by size, weight, vibration sensitivity, and platform stability requirements.
