Blighter A800

System Overview

What It Is

The Blighter A800 is a multi-mode 3D electronic scanning radar developed by Blighter Surveillance Systems for persistent detection and tracking of small drones, ground targets, and maritime threats. Using advanced FMCW Doppler technology with no moving parts, it provides reliable, maintenance-free operation for long-term counter-UAS surveillance.

How It Works

The A800 uses Frequency Modulated Continuous Wave (FMCW) Doppler technology with an active electronically scanned array to detect and track small moving targets in three dimensions. The radar distinguishes drones from birds and clutter using micro-Doppler signature analysis, which identifies the characteristic blade rotation patterns of multi-rotor drones. With no mechanical moving parts, the radar offers exceptional reliability and minimal maintenance requirements.

Primary Capability

Wide-area 3D radar detection and tracking of drones, people, vehicles, and other targets for C-UAS and security.

Combat Record / Operational History

Deployed globally for border security, critical infrastructure protection, and military counter-UAS applications. Component of the AUDS system.

Overview

The Blighter A800 3D multi-mode radar is a leading sensor for counter-UAS applications, providing wide-area persistent detection and tracking of small drones using advanced electronic scanning technology. Developed by Blighter Surveillance Systems in the United Kingdom, the A800 has earned a strong reputation for its ability to reliably detect and classify small drone targets while rejecting clutter from birds and other false alarm sources.

Development History

Blighter Surveillance Systems, based in Essex, UK, has been developing electronic scanning radar technology for over two decades. The A800 represents the latest generation of their FMCW radar family, incorporating 3D detection, AESA technology, and advanced signal processing specifically optimized for the counter-UAS mission. The company's radar technology is notably used as the detection component of the AUDS integrated counter-UAS system, where it has seen operational deployment.

Operational Concept

The A800 is typically deployed at fixed sites or on masts around a perimeter, providing continuous surveillance of the surrounding airspace. The radar's electronic scanning covers a wide sector without mechanical rotation, offering rapid revisit rates and high reliability. When a potential drone target is detected, the radar's micro-Doppler analysis examines the target's signature for the characteristic blade rotation patterns of multi-rotor drones, helping classify the detection as a drone rather than a bird or other false alarm. Confirmed detections are passed to command-and-control systems for operator assessment and potential effector engagement.

Future Development

Blighter continues to enhance the A800 with improved signal processing for detection of smaller and more evasive drone targets, extended range performance, and better classification algorithms leveraging AI and machine learning. Integration with a broader range of C-UAS command and control platforms is also a development priority.
