The ability to control and adapt a platform’s signature against threats in the battlefield is key to its survivability. With expertise in the design, analysis and reduction of platformsignatures, coupled with an intimate knowledge of sensor systems and technologies,we deliver
effective signature management solutions.
Our capabilities in signature management extend across visual, infra-red, Radio Frequency (RF) and acoustic threats. We use world leading codes for the prediction and analysis of signatures and deploy a wide range of techniques to manage platform signature. We deliver a true multi-spectral capability to our customers and offer prediction, analysis and implementation solutions to a wide range of signature issues.
Long established expertise in visual performance understanding has resulted in the generation of a family of predictive models,code name ORACLE.
These models enable prediction of the performance of the naked eye, or enhanced vision through various optical sensors. As the visual signature is determined, reduction schemes can be trialled to optimise the solution delivered.
Moving into the infra-red (IR) part of the spectrum, the SIRUS infra-red signature prediction code provides the ability to model the IR emissions from jet plume and hard bodies for complex 3D geometries. Modelling can be performed across a range of realistic background environments and is applicable to platforms and systems operating in the air, on land or at sea.
To counter threats from sensors operating in the RF bands, the ATC has a comprehensive offering covering modelling, design and the production of materials and structures to modify and adapt the Radar Cross Section (RCS) of a platform. Our codes enable us to accurately predict the RCS for structures which need to be stealthy such as missiles, aircraft or ships. The methods used include full Maxwell solvers (finite difference, finite element and boundary element techniques), asymptotic methods (physical optics,physical theory of diffraction) and novel integral equation methods for obtaining the RCS of ducts containing radar absorbent material.
Code developmental activity includes hybrid codes to enable the analysis of larger structures and multi-level fast multi-pole techniques
supporting more efficient computation.
Once the modelling and analysis activity has identified design solutions to control the RCS, we offer a range of implementation solutions delivered through our specialist manufacturing facilities. We are the leading UK designer, developer and manufacturer of microwave absorbers including Radar Absorbent Materials (RAM), with a long history of delivering stealth solutions onto platforms across air, land and sea environments. Our continuous development activity sees us working in partnership with end users and platformmanufacturers to develop new materials and design future low observable platforms,including the development of techniques for active adaptive signatures.
Our acoustic solutions focus primarily on the reduction of self-noise from submarines. Solutions include active control of machinery raft suspension, damping of concertina mode noise in hulls and application of fluid dynamics to identify solutions to reduce noise emissions from flow within pipes.
We offer a true multi-spectral capability and can deliver prediction, analysis and production of solutions to address a range of signature management issues.
