In design and remote sensing of aircraft or complex structures
electromagnetic scattering has a central role.
Engineers may use radar scattering in optimising the
design of shape and of material properties, with collaborating scientists
often in geographically remote sites.
This information raises problems of visualisation of
complex scattered radar patterns and high dimensional data, and its
incorporation into the engineering process.
Visualisation tools are being developed to allow interactive
examination of scattering patterns across the structure surface,
and of the radar cross-section in 3D space around, or fields within or on
The high computational cost makes these particularly demanding. Interpolation is first used to provide
higher-resolution interrogable data, from values calculated at an
initial set of points. Several representations can then be applied,
to allow investigation of key features in radar data, their causes and
how they might be modified.
Results will be available to remote users via the web portal,
who can execute scattering code or launch the visualisation
software. The user can for example view isosurfaces, ie surfaces of
equal intensity in 3D; alternatively colour contour plots which reveal
high-intensity areas by steering a cutting plane interactively along
the structure, in a virtual 'fly-through'.
