SHEERGARD Ship Radome

Electromagnetic Windows

Electromagnetic Windows to protect and conceal antennas

With proven reliability and low lifecycle costs, custom-designed SHEERGARD® electromagnetic windows protect and conceal sensitive radar and communication installations. Suitable for sensitive, high-security environments and system compatible for commercial use.

SHEERGARD® electromagnetic windows are virtually transparent to electromagnetic energy in the frequency ranges found in contemporary systems. Easily integrated into existing substructures, design flexibility allows us to partner with you to deliver customized solutions to fit your application.

Product Details

SHEERGARD® electromagnetic windows have several benefits which deliver excellent performance and lifetime value. Custom design engineered by a dedicated team of structural, mechanical and PE licensed engineers, their woven substrate fabric with applied coatings provides high tensile strength and tear resistance. SHEERGARD materials also have a vast temperature range (typically from -60°F (-51°C) to +500°F (260°C)) and are Teflon coated, enabling lifelong hydrophobic performance and ensuring you never need to reapply a surface finish. Unsurpassed RF performance (featuring dielectric constants of less than 2.8) results in minimal energy scattering into the antenna sidelobe and mitigates against cross-polarization and noise temperature. Crucially, Sheergard has faced the most robust environmental testing. It offers environmental protection in even the most extreme conditions (including winds over 210mph (340km/h). It is also resistant to hail, offers low thermal conductivity and good RF performance at high incidence angles (up to 70 degrees) Consequently, these products combine technical excellence with inherent durability.

Rigorous testing standards

Saint-Gobain Composite Solutions rigorously tests all SHEERGARD® radome products via software-modeled analytics, lab-scale material characterization, and most importantly, directly relevant application testing. Every SHEERGARD® radome complies with strict MIL.STD.810 testing – the military-leading standard for all environmental conditions including temperature, humidity, salt, fungus, and many more. Software modeling such as Finite Element Analysis and Thermal Analysis can yield information on deflections, factors of safety, and thermal management requirements. Application tests such as physical hail storm testing, destructive fabric testing, and real-life application exposure reveal key learnings in creating a truly optimized product. Our testing begins during the co-development process to develop relevant tests and gather data that allows us to create market-ready solutions quickly.
