Complex Axisymmetric Target Signatures (CATS)

Overview

CATS (Complex Axisymmetric Target Signatures) is a 3-dimensional computer code for the radar cross section analysis of objects that exhibit axisymmetric, or rotational symmetry.

Applications

CATS is a 3-dimensional code to compute mono-static radar cross section from any observer orientation.

Benefits

• In CATS, the scattered fields and radar cross section are obtained from rigorous determination of the surface currents induced on the scatterer by the incident excitation field.
• Reduced computer core memory requirements due to linear equations that must be solved to find the Fourier coefficients decouple into separate problems for each Fourier mode.

Product Features

• Rigorous computation of surface currents
• Surface co-ordinates in (Z,R) plane and azimuthal angle of revolution
• Anisotropic impedance with tangential and azimuthal components
• Tent-shaped basis functions
• Surface currents can be represented as Fourier series
