AZE radome

P.E. Composites Limited (PECL) has many years of experience in the design, manufacture, testing and installation of composite radomes and composite/hybrid structures for hostile and exacting environments where a high specification and performance is required from both sensor and structure.

With a view to maintaining the Company’s leading position in industry, the PECL engineering team remain abreast of developments in composite materials, technologies and processes which provides a valuable base in support of our ongoing PECL privately funded R&D programme.

A large volume of PECL innovative design finds its way into military platforms, principally submarines.

Our customers’ challenging requirements can quickly be transformed into a design and costed proposal.

A typical example, detailed below, is used to illustrate such a requirement for a high specification solution for a submarine borne broadband RF communications and RESM sensor.

PECL Low Above Water Signature (AWS) RADOME.

The top right illustration shows a composite submarine sensor radome fully compliant with the environmental and mechanical requirements demanded by the current UK MoD DEF STAN for Royal Navy Submarines.

The principal design aims for the radome were to provide:

  • high quality RF performance. (from VLF to above Ka band)
  • solutions for AWS issues. (RCS, Visual, and address IR management options).
  • a product that meets or exceeds the current UK MoD DEF STAN’s for Royal Navy Submarines

This unique RCS reduction design embodies the use of advanced composite materials, a bespoke reinforcement design, a low dielectric resin matrix with high mechanical performance, with the unit manufactured utilising a specialised process.

The radome shown achieves:

  • a low RCS signature at operational threat angles
  • a high performance as a sensor antenna enclosure for broad-band application providing a low RF attenuation path through radome (0.9dB (trend 0.7dB) maximum up to K band and 1.2dB (trend 0.9dB) maximum up to Q band)
  • a low mass with high mechanical and environmental specification performance
  • high durability and long life
  • predictable and repeatable performance
  • has a specialist “RF friendly” solar reflective coating to protect enclosed active components
  • with an outer coating “design ready” for the implementation of visual signature reduction to customer specification
  • design ready to embody IR reduction techniques using QinetiQ technology

This design can be part of an RCS reduction exercise for an above water sensor assembly/structure and is ideal when used in conjunction with a composite RCS design structure or protective skirt such as the PECL skirt illustrated, which utilises a QinetiQ CA RAM design that will exceed currently specified requirements.
