Anti-jamming antenna AJ800

The AJ800 Series is a fully integrated, high-performance Controlled Reception Pattern Antenna (CRPA) solution. It incorporates an 8-element antenna array and an advanced Digital Antenna Control Unit (DACU) into a single, compact package. Specifically designed to suppress interference in the B1/L1/E1 & G1 frequency bands, it employs a self-developed, proprietary anti-jamming System-on-Chip (SoC) that executes a sophisticated polarization-space-time-frequency joint anti-jamming algorithm. This multi-domain approach allows the AJ800 to dynamically form deep nulls in the direction of jammers, effectively suppressing multiple interference threats simultaneously and ensuring a clean, reliable signal for the UAV's navigation system.

OPERATIONAL HIGHLIGHTS

 

Product Advantages for UAVs

Maximized Signal Integrity in Hostile RF Environments: The AJ800’s advanced adaptive nulling technology is a key method to counteract oppressive interference at the receiving antenna end. By intelligently nullifying up to 7 distinct jamming sources concurrently, it provides an unparalleled level of protection against both targeted attacks and congested spectra.

Mission Assurance and Drone Survivability: Ensures continuous and precise positioning data, which is fundamental for navigation, target acquisition, and the safe return of valuable assets. This capability is crucial for operations in denied or contested areas.

Proven, Multi-Domain Algorithmic Defense: The built-in polarization-space-time-frequency algorithm leverages every available characteristic of the incoming signal and interference to perform optimal suppression. This comprehensive approach offers a more robust and effective countermeasure than single-domain methods.

Integrated and Ready-to-Deploy Design: Combining the CRPA array and DACU into one unit simplifies integration onto UAV platforms, saving critical space, weight, and power (SWaP), and reducing system complexity for manufacturers and operators.

The AJ800 Series is essential for UAV platforms where navigation failure is not an option:

Defense & Security Operations: Enabling reconnaissance, surveillance, and strike missions in electronically contested environments where GPS jamming is a prevalent threat.

Critical Infrastructure & Border Patrol: Protecting drones tasked with long-endurance monitoring of pipelines, power grids, and national borders from intentional or accidental interference.

Public Safety & Disaster Relief: Ensuring that UAVs used in emergency response, firefighting, and search-and-rescue can operate reliably amidst dense emergency service communications and potential RF chaos.

High-Value Commercial & Industrial Missions: Safeguarding drones used in precision agriculture, surveying, mapping, and logistics that require guaranteed positioning continuity for data integrity and operational safety.
