IDS UK was incorporated in 2002 to provide specialist electromagnetic (EM) modelling software and consultancy services to customers in the UK MOD and Defence Industry. The company offers EM modelling capabilities in land systems, naval systems, air navigation, aeronautical and top end products for surface penetrating radar. They are involved in international research activities for military through-wall radar.
IDS UK is an independent UK SME based near Southampton and is part of the IDS group who have offices in Pisa, Rome, Varese, Brazil, Australia and Canada. The IDS group have dedicated 25 years to developing EM modelling software tools and the design and manufacture of surface penetrating radar.
Capabilities
CAD Model Development
IDS UK have extensive knowledge and experience of CAD development for EM modelling, having developed dozens of CAD models from many different source formats. IDS UK will advise on the appropriate level of complexity that is required for a CAD, depending on the specific requirements of the task.
Electromagnetic Modelling
A complete EM modelling service is offered by IDS UK from understanding the requirement, to CAD, antenna and materials creation, to running the software and interpreting results.
The input to the software is a mesh formed around the CAD. Meshes are constructed using the IDS automatic meshing tool. This is used for all frequencies from HF through to microwave and is available as a commercial product.
Advanced antenna models and materials are then linked to the meshes to accurately simulate the operational EM environment.
Force Protection
Modelling the EM environment for effective force protection is of particular interest. Current operations require large numbers of antennas to be deployed on limited roof space, which has forced jamming and communications equipment into close proximity. The result is a very complex EM environment where the total equipment fit needs to be considered to ensure mission success.
IDS UK can model most types of antennas / jammers operating together. This can be for a single platform or for multiple vehicles when assessing convoy protection or interoperability.
Antenna Coverage Example
EM modelling is a highly technical domain for which IDS have developed methods of simplifying and condensing results to aide customers’ understanding. An example, shown here, has taken many single frequency data results and combined these into an easily interpreted plot. The blue polar plots on the left represent individual frequency results (in practise there could be hundreds of these); these are combined into one polar plot where colours show different degrees of coverage. Finally a traffic light system of good performance, uncertain performance and no link is employed, along with a top view of the vehicle to clearly demonstrate in which directions the installed antenna can be expected to show degraded performance.
Terrain Modelling
The EM modelling capability that IDS UK offer can include the modelling of geographic features and man made structures. Thus the impact of buildings in an urban environment or the presence of other vehicles on the EM environment can be investigated.
The IDS capability has been in regular use since 1987 and has been extensively validated.
EDF Software
The Electromagnetic Design Framework (EDF) used by IDS UK is used for:
- CAD development
- CAD to EM mesh creation
- Antenna performance simulations with structure and other antenna interaction (EMC, EMI)
- RadHaz safety analysis (personnel, equipment, fuels and/or ordnance)
- Modelling the impact of terrain on antenna link performance
- Radar cross section prediction
- Infrared signature prediction
- Full vehicle EM integration analysis
The IDS EM modelling software is mature, validated, has been deemed fit-for-purpose in independent tests.
