Low-altitude security · 10 configurations
Compare OMNI UXV radar, RF, electro-optical, jamming and navigation-response components for layered low-altitude security projects.
Category brief
A counter-UAS deployment is a layered sensing and response architecture. Radar, RF detection and electro-optical confirmation solve different parts of the problem; site topology, background RF noise, target profile and response authority determine the right combination.
Active countermeasures can be restricted or prohibited in many jurisdictions. OMNI UXV treats detection, identification, tracking and response as separate design decisions, with project configuration subject to destination-country law, spectrum authorization and end-use review.
Product line
Low-altitude detection
The NI-R5000+ is an active radar sensor for low-altitude situational awareness. It provides track data to a command platform and can cue optical or radio-frequency sensors for layered verification.
Compact phased-array sensor
The NI-SR3000 is a compact array radar for sector defense and infrastructure protection. Its exact detection envelope depends on target radar cross-section, installation height, terrain and electromagnetic conditions.
360-degree detection
The NI-QR5000 uses an omnidirectional array arrangement to maintain persistent awareness around a protected location. It is normally combined with RF detection and electro-optical confirmation.
Passive spectrum awareness
The NI-S3000 monitors relevant spectrum for drone and controller activity. It adds passive detection, signal characterization and early warning to a layered counter-UAS architecture.
Visual confirmation
The NI-C3000 is the visual verification layer in a counter-UAS sensor stack. It receives target cues, tracks the object and supplies visible-light or thermal imagery to operators.
Electronic countermeasure
The NI-J3000 is a directional countermeasure component for legally authorized deployments. Frequency plans, operating power and use procedures must be approved for the destination jurisdiction and site.
Layered electronic response
The NI-JG5000 combines configurable radio interference with simulated-navigation signal response. It is intended only for approved government or critical-security environments with a documented spectrum plan.
Controlled navigation response
The NI-G3000 generates simulated navigation signals to alter the response of compatible unauthorized aircraft. Deployment requires site-specific authorization, safety procedures and integration with a verified detection layer.
Portable RF reconnaissance
The NI-S2000H provides mobile teams with spectrum scanning, direction finding and compatible-protocol data. It can operate independently or contribute observations to a wider command platform.
Mobile detection and response
The NI-SJG2000B packages wideband detection and controlled countermeasure functions for mobile teams. It is designed for authorized force protection, patrol and temporary mission security.
Technology guide
A counter-UAS system combines detection, tracking, classification, identification, evidence and an authorized response workflow. It is not a single counter-drone radar or RF detector. Each sensing method observes different target behavior, and its performance changes with terrain, clutter, background radio activity, weather and the target set used in testing.
A buyer comparing a counter-UAS system supplier should begin with the protected volume, credible approaches, warning time and operator decision. The resulting architecture may be detection-only. Active RF or navigation-response functions are separate design and authorization questions that must not be assumed from the availability of hardware.

Radar can observe motion and support continuous tracks, including targets that do not transmit a familiar protocol.
Selection note: Define target size, speed, altitude, clutter and probability-of-detection test routes before comparing range.
RF sensing is passive and can add identification context when the aircraft or controller emits a supported signal.
Selection note: Test against the actual spectrum environment and include autonomous, silent and unfamiliar links in the threat model.
A camera layer can confirm a cued target and preserve visual context, but acquisition depends on cue quality, light and atmosphere.
Selection note: Measure cue-to-image time, target retention and useful image quality across representative backgrounds.
Jamming or navigation-response equipment may form a separate project layer where law, spectrum and safety controls allow it.
Selection note: Confirm legal authority, bands, safety boundaries, abort conditions and immutable action logging before configuration.
Map approach corridors, clutter, protected volume, target types and acceptable alert latency.
Use complementary radar, RF and visual confirmation to reduce blind spots and nuisance alarms.
Confirm who may act, which radio bands are lawful and what evidence must be retained.

Before requesting a quotation
No. Small aircraft, autonomous flight, terrain masking and congested RF environments create different blind spots. Layered sensing and site testing are normally required.
No. Availability depends on destination, end user, spectrum rules and export controls. A compliant project may be detection-only or integrate a locally authorized response layer.
The evaluation should use site-specific clutter and representative targets. Detection probability, track continuity, classification confidence and false-alarm rate should be measured together.
