Galileo-EME – Large Platform Electromagnetic Engineering Design Framework


Galileo-EME picture of the framework for large platforms

Radar and Infrared Signatures

The primary means of avoiding detection is to attempt to appear invisible by reducing RADAR (RCS) and Infrared (IR) signatures. This goal can be achieved by considering a ship’s or an aircraft’s RCS and IR signatures during the design process, by adjusting the platform’s geometry, and by using materials that help to reduce these signatures. Galileo-EME is a modular framework for the electromagnetic simulation of complex platforms and includes both RCS and IR prediction capabilities. These features can provide an effective workflow for signature management of aeronautical and naval platforms at the component and system levels, thereby allowing manufacturers to start optimizing a platform’s design at the earliest stages.



Viraf-rcs-polar-plot-analysis-of-military-aircraftGalileo-EME is specifically designed to provide an integrated environment for signature management of aeronautical platforms, both at the component and system levels. It is a modular framework which can offer both RCS and IR signature prediction and management allowing aircraft manufacturers to start optimizing an aircraft’s design at the earliest stages.

Galileo-EME includes a suite of advanced modeling and prediction tools which have been extensively validated through IDS’s 25 years of experience providing radar and infrared signature simulation and measurement services. Feedback from IDS’s engineers is also used to continuously update and improve the tools and working procedures with the aim of reducing the time and cost for an optimized aeronautical or naval design solution.

Galileo-EME provides a full framework for the management of complex designs, thanks to the project/version data organization, streamlined workflows, input, output, settings and results history tracking and the ability for multiple users to work on the same project. It includes tools to interface with most common commercial CAD software as well as an advanced meshing tool to generate numerical models to be used by the signature prediction codes.

Galileo-EME is a modular framework which includes:

  • RCS module for the prediction of the RCS
  • IR module for the prediction of the IR signature

The Galileo-EMEframework is based on a client-server software architecture: pre- and post-processing functions are performed on the client while computations run on the server. This architecture allows several configurations (from single client / single server to multiple clients / multiple servers) to meet the user’s needs.
