U.K.'s Blighter Unveils Radar That Detects Intruders 15km Away Using Just 4 Watts

U.K.-based radar manufacturer Blighter has introduced its new B422LR smart border surveillance radar, capable of detecting a person at 15 kilometers (9.3 miles) using just 4 Watts of power — equivalent to the power consumption of a mobile phone or LED bulb.

The company says the new radar enables earlier detection of intruders and reduces costs by allowing border security operators to monitor a wider area with fewer radar units. The extended detection range increases the surveillance footprint to 707 square kilometers, compared to 201 square kilometers with earlier 8-kilometer-range systems.

The B422LR radar is a solid-state, export-friendly system using pure electronic scanning with no moving parts. It offers up to 360-degree coverage and requires no active cooling, making it suitable for remote locations powered by solar panels.

The radar uses frequency modulated continuous wave (FMCW) transmission with micro-Doppler detection, requiring less bandwidth and far less power than conventional security radars. Its low size, weight, and power (SWaP) profile makes it easier to deploy in remote and harsh environments.

Blighter’s B422LR is integrated with the company’s BlighterNexus AI-assisted hub, which supports command and control (C2) system integration and automates radar configuration for changing weather or operational needs. The software provides a real-time, unified border picture and reduces training and setup time.

Blighter emphasizes that its radar systems are not subject to U.S. ITAR restrictions or E.U. dual-use regulations. This allows faster procurement and deployment by international customers for both commercial and military uses.
