Information about cadRCS

STEALTH DESIGN

This unique software product from Css, Germany, provides high resolution Radar Cross Section (RCS) calculation based on 3D CAD data.

cadRCS is an inexpensive solution if you want knowledge about the RCS of your object(s). A user-friendly GUI based graphical display enables precise identification of radar reflecting areas. It also provides mono-pulse pictures, showing where on the object a radar seeker will aim. In this way, the simulator permits continuous stealth assessment of ships, aircraft and other constructions.

In other words – this software transforms a highly complex theoretical field into a practical tool that can be operated by everyone.

ACCURATE AND RESPONSIVE

The highly advanced 3D calculation technology used in this software is based on more than 30 years of experience in RCS measuring.

Comparison with actual RCS measurements reveals an exceptional accuracy. Naturally, the accuracy depends on the quality of the 3D CAD model.

Also when comparing ship measurements with calculations it is important to know the roll and pitch of the ship as this has an impact on the RCS.

cadRCS THEORY

The theory used in cadRCS is unique and has never been published. The theory is developed by the owner of Css Gert Albert Lindqvist. He has a background in Theoretical Physics and more than 30 years of experience in RCS measurements. The theory will remain a Css property.

cadRCS CALCULATION TIME

The calculation time is dependent on the reflection profile of the object and the desired accuracy. According to several of our users, it is faster and much more accurate than all other RCS prediction tools.

RCS CALCULATION ADVANTAGES

cadRCS can calculate RCS of any 3D object described by a 3D CAD file.

A great advantage of having a CAD-model of the object in question is that all aspect angles can be examined – which is not possible if only measurement methods are applied.

Using the CAD-model together with cadRCS offers the opportunity to train the operational staff in examining different attacks, thus training them in ensuring that they are in the best situation for using decoys or other methods to improve their survivability.

NEW cadRCS FEATURES WITH Windows 10

With the Windows 10 everything is 64 bit and cadRCS calculations must be accurate and were always performed in 64 bits also on the old 32-bit machines. Of course, the calculations are much faster in Windows 10, but also new features are then possible.

It is now possible to calculate on images that are up to 1024×1024 pixels in size and the maximum number of facets can be up to 5.000.000 facets.

Radar issues you cannot calculate with cadRCS

SAR/ISAR IMAGES

cadRCS cannot calculate SAR/ISAR images directly, but it can make results for input to a SAR/ISAR processor.

cadRCS is primarily designed to make the same results as a normal operational radar.

MOVING TARGET INDICATION

Moving target indication (MTI) – please see wikipedia.org

cadRCS cannot calculate the speed due to the lack of input of the velocity in the input parameter setup.

MTI is often used by radars looking at moving targets as the technique gives a much better signal to noise ratio.

OTHER SUBJECTS

The owner of Css also has expertise and experience in the following areas:

  1. Stealth development, especially on sandwich constructions.
  2. Free space radar measurements of small targets.
  3. Development of active decoys. Computer controlled decoys give a much better signature and they are reusable, environment friendly and can adapt to different threat situations.
