Blighter Surveillance Systems has introduced a striking advancement in ground movement radar technology with the B422LR, a long-range border surveillance radar capable of detecting a person at 15 kilometers — all while consuming just 4 Watts of power. To put that in perspective, this is roughly equivalent to the energy demand of a mobile phone charger or a single LED light bulb, making it a standout in a field often dominated by high-power, bulky installations. The system achieves this range with exceptional efficiency thanks to its solid-state, low-power electronic scanning platform, paired with no moving parts, no active cooling, and a power profile that supports full solar operation — a combination aimed squarely at rugged, remote national borders where infrastructure is scarce or impractical.
This new system dramatically increases the monitored area compared to previous models. With a 15km person-detection range, each unit can surveil up to 707 square kilometers, compared to just 201 square kilometers for radars limited to an 8km range. In real-world deployments, that shift has strategic and financial implications: fewer radar towers, reduced infrastructure costs, earlier threat detection, and the operational flexibility that comes with longer standoff capabilities. Border security forces, often working under severe environmental and logistical constraints, can cover significantly more territory with fewer installations — a clear force multiplier.
Blighter’s B422LR relies on frequency modulated continuous wave (FMCW) radar transmission, combined with micro-Doppler signal processing to distinguish and track slow-moving or crawling human targets up to 6.4km away. Unlike conventional pulsed radar systems, which require higher peak power and broader bandwidth, FMCW radars operate with a narrow communications bandwidth and minimal energy requirements. This not only makes the system more covert and energy-efficient but also enhances performance in cluttered environments and across adverse weather conditions — precisely the terrains and climates where illicit crossings or incursions often occur.
Integration is also a key strength of the B422LR. It connects seamlessly to BlighterNexus, the AI-powered hub that serves as the system’s bridge to command and control (C2) platforms. The Nexus software simplifies installation and automates operational tuning in real-time, continuously adapting to environmental changes and ensuring optimal performance across a fleet of deployed radars. This AI-assisted interface reduces both operator training time and long-term support overhead, while presenting a unified, real-time operating picture across vast border landscapes.
What makes Blighter’s radar offering especially compelling for international customers is its regulatory status. Unlike many advanced security technologies tied up in U.S. ITAR or EU dual-use export restrictions, the B422LR is export-friendly, significantly easing the path to acquisition and deployment. This opens up both civil and military markets in regions where sovereignty concerns, budget constraints, or political barriers make access to tightly controlled systems problematic. For governments seeking an advanced, yet practical surveillance solution, this strategic regulatory advantage translates directly into faster deployments and simpler procurement.
Blighter’s latest system demonstrates how precise engineering and clever design can redefine capabilities in border surveillance. The B422LR doesn’t just push technical boundaries — it reframes what’s possible when power efficiency, AI-driven operation, and long-range performance are combined into a compact, solar-friendly package. As demand for persistent, cost-effective border surveillance intensifies around the globe, Blighter’s radar may well become a defining component of next-generation perimeter defense.
