In the past, electromagnetic, infrared and radar cross section assessment would be performed through physical measurements. These would be conducted during sea trials following the completion of the new vessel and prior to its commissioning. At this stage the scope and scale of any modifications to the ship's design are limited, expensive and time consuming.

Ship EDF allows these activities to start during the early conceptual design phase and to continue all the way through the design and construction phases to the final acceptance tests. It provides detailed models and simulations of the electromagnetic environment, infrared signature and radar cross section of a new ship's design and makes use of advanced electromagnetic solvers as well as analytical, computational and design procedures which have been internally developed and validated in a continuous process since 1982. These aid the designer in making changes and selecting the best choices during the critical early design stages.

It includes tools to manage a project's workflow, track its history and to store the data in a database to enable multiple projects to benefit from the same validated materials and equipment data.

Modules:

Ship EDF is comprised of four individual modules: Radar Cross Section (RCS); Infrared (IR); Electromagnetic Engineering (EME) and Below Deck.

Benefits:

  • Allows electromagnetic risk assessment to be performed prior to construction, saving time and money.
  • High quality solvers and analytical, computational and design procedures are supported by verified measurements.
  • Advanced post processing features which are built on IDS’s extensive experience in military naval engineering.
  • Enables the designer to easily test different configuration options resulting in the most effective designs.
  • Project versioning and traceability for highly efficient design operations.
  • RCS, IR and EME design all in the same environment allowing changes in one to be easily and quickly tested for the other two.

 The computational resources required for electromagnetic simulation can increase very rapidly depending on the size of the problem to be analyzed.

In this regard, warship design is typically very demanding and maintaining the required efficiency and effectiveness of the processes involves correctly scaling the simulation hardware and software structure.

To allow the required tailoring, Ship EDF can be deployed on a Windows based computer network in any of the three configuration levels depicted below, where the number of clients and computational servers can be set to best match the user’s performance requirements.
