A new radar system developed in the UK is setting a new benchmark in border surveillance by combining extended detection range with low power consumption and AI-driven performance. The Blighter B422LR radar can identify a human target at distances of up to 15 kilometers and track crawling individuals at 6.4 kilometers, all while operating on just 4 watts of power—comparable to a household LED bulb.
According to the press release, this electronically scanned radar (e-scan) delivers full 360-degree coverage without the need for mechanical rotation. It achieves this using frequency-modulated continuous wave technology and micro-Doppler target detection.
Designed with remote operations in mind, the B422LR system can be deployed in off-grid areas using solar power and does not require active cooling mechanisms. This makes it particularly suitable for long-term, unattended border monitoring across challenging terrain or large expanses. One unit can cover an area of over 700 square kilometers—equivalent to roughly the size of New York City.
The radar is further enhanced by its integration with BlighterNexus software, which enables connection to command-and-control networks. Operators receive a real-time unified situational picture, critical for rapid decision-making. The radar’s embedded AI features help automate deployment, calibration, and adaptation to environmental conditions, effectively reducing the need for intensive training or on-site technical teams.
From a regulatory perspective, the B422LR avoids complications commonly associated with export controls. It is not subject to the U.S. ITAR (International Traffic in Arms Regulations) or the EU’s dual-use export control rules, streamlining international sales and deployment.
With the growing demand for intelligent border monitoring solutions worldwide, the B422LR offers a compelling mix of performance, operational simplicity, and export flexibility. Its long-range capabilities, low logistical footprint, and AI integration position it as a competitive solution for modern border and perimeter defense scenarios.
