Innovating Electronic-Scanning Radar Solutions for Global Security

Introduction

Blighter Surveillance Systems Ltd, headquartered near Cambridge, UK, is a leading designer and manufacturer of electronic-scanning (e-scan) radar systems. Established to address the increasing demand for advanced surveillance technologies, Blighter specializes in solid-state radar solutions that provide persistent, all-weather, and day-night detection capabilities.

Company Overview

Founded in 2015, Blighter Surveillance Systems operates within Europe’s largest technology cluster, granting it access to a skilled talent pool and fostering innovation. The company focuses on developing radar systems that detect distant moving objects without relying on mechanical components, thereby enhancing reliability and reducing maintenance needs.

Technological Advancements

Blighter’s radar systems employ Passive Electronically Scanned Array (PESA) technology combined with Frequency Modulated Continuous Wave (FMCW) and Doppler processing. This integration allows for rapid scanning, low power consumption, and the ability to detect a wide range of targets, including drones, vehicles, and individuals, even in complex terrains.

Product Portfolio

Blighter offers a diverse range of radar products tailored to various security applications:

• A800 Series Advanced Air Surveillance Radars: The A800 series represents Blighter’s latest generation of air security radars designed for enhanced detection of small and low-signature aerial threats, including drones and UAVs. These radars provide extended range and higher resolution, offering 360° coverage with improved target discrimination capabilities. Equipped with advanced signal processing and adaptable configurations, the A800 series is suitable for critical applications such as counter-UAS operations, base protection, and urban security environments.
• A400 Series Air Security Radars: Designed for detecting small unmanned aerial systems (UAS) and other airborne threats. These radars provide 360° coverage and can detect targets at distances up to 20 km.
• B400 Series Ground Surveillance Radars: Suitable for monitoring ground movements, these radars can detect vehicles and individuals at ranges up to 32 km. Their solid-state design ensures durability and low maintenance.
• C400 Series Coastal Security Radars: Specifically developed for coastline surveillance, these radars offer extended range and are resistant to environmental challenges such as saltwater corrosion.
• B422LR Long-Range Border Surveillance Radar: Capable of detecting a person at 15 km with just 4 watts of power, this radar system is ideal for monitoring vast border areas with minimal energy consumption. (blighter.com)
