Passive Radar for Detecting Aircraft Without Emitting
The case for listening rather than shoutingEvery conventional radar has the same vulnerability: it announces its presence. The moment a radar transmits, it becomes detectable, locatable, and, if the adversary is sophisticated enough, targetable.
International Patent Grants for Pain Management Technology
Plextek and Remedee Labs, the French healthtech start-up, are proud to announce that patents covering key aspects of the millimetre-wave antenna technology at the heart of Remedee’s endorphin-stimulating wristband have been granted in China, Europe, and the United States. The device has since become the first CE-marked medical device in Europe approved for the treatment of chronic pain.
How Do You Radiation-Test a Complex IC?
How Do You Radiation-Test a Complex IC?When a radiation-hardened component exists for your space-based electronics application, the path is relatively straightforward, when budget allows.
How technology transfer is reshaping sovereign security
From automotive to critical infrastructure, cross-sector technology transfer is reshaping sovereign security. The challenge of monitoring Critical National Infrastructure (CNI) is evolving at speed. As nuclear decommissioning sites progress through their lifecycle, security risks decrease, yet traditional high-security monitoring systems remain expensive and resource-intensive.
Plextek receives a King’s Award for Enterprise for Innovation 2026
Plextek has been honoured with a King’s Award for Enterprise for Innovation, marking a major milestone for the business.
Seeing clearly in orbit: the turning point for space radar
As the space sector races toward a more commercial, congested, and contested environment, 2026 will be the year small-SWaP radio and radar technology finally shifts from niche to mainstream. For years, radar was considered too heavy, too power-hungry and too complex for smaller satellites, but that era is over. The next generation of commercial, defence, and scientific missions will depend…
Plextek wins place on MOD’s DDAD Framework
Plextek has been selected as a supplier on the £180 million Digital Decision Accelerators for Defence (DDAD) Framework, supporting the British Army’s ASGARD programme – its flagship Transformative Capability Initiative focused on battlefield decision-making and digital targeting.
mmWave radar: balancing resolution and practicality in space
Space environments present unique sensing challenges. Systems must detect objects ranging from paint flecks to spacecraft components, operate reliably in harsh conditions, and do so with minimal mass and power consumption. mmWave radar addresses these requirements, providing millimetre-scale resolution with practical implementation that suits the realities of space missions. But how does…
Plextek takes part in TeenTech Festival Sussex
Plextek joined organisations from across the UK at the Amex Stadium in Brighton for the TeenTech Festival. The event welcomed 300 Year 8 and 9 students from the region, giving them the chance to take part in hands-on science, engineering, and technology activities designed to broaden their understanding of future career paths.
Beyond policy: how industry must deliver ESA’s Zero Debris Vision
Space needs to be kept clean, and this is becoming increasingly hard as commercial and defence activities ramp up. The European Space Agency’s recently published Zero Debris Technical Booklet, developed through a collaborative community effort bringing together industrial and institutional perspectives, represents a critical step forward in addressing one of the most pressing challenges facing…
How radar works
Imagine you are standing in a pitch-black room, firing rubber balls in every direction. Some will hit surfaces that bounce them straight back at you...
Why radar should be on your radar
Space missions demand sensors that work in brutal conditions. Cameras go blind in direct sunlight or complete darkness, and, as demonstrated in the video below, LiDAR systems confused by dust particles. Radar just keeps going.
Accelerating the next generation of Electromagnetic Warfare
Warfare is being redefined. As the UK’s 2025 Strategic Defence Review (SDR) outlines, rapid advances in technology and changing conflict dynamics are transforming both the threat and the way nations need to respond. A new Cyber and Electromagnetic (CyberEM) Command and a commitment of £1 billion to develop a ‘Digital Targeting Web’ to link UK armed forces’ weapon systems underlines this…
Addressing the escalation in GNSS Spoofing with Data Fusion
The grounding incident involving the MSC ANTONIA serves as a clear reminder of the critical need for resilient navigation systems in the maritime sector. As GNSS jamming and spoofing become more frequent, particularly in high-risk regions, vessels must be equipped with systems that can maintain accurate positioning even when satellite signals are compromised, explains Freddy Saunders, Senior Data…
Driving radar innovation for Space in the CLEAR Mission
With the successful completion of Phase 2 of the mission CLEAR, led by in-orbit servicing company ClearSpace, we are proud to announce our pivotal role in achieving the major technological milestones that bring the mission closer to reality.
Why Radar is Becoming Essential in Mission Assurance
As the next era of lunar exploration begins, the tools we use to guide spacecraft and ensure safe landings are becoming just as important as the missions themselves.
