Complex Axisymmetric Target Signatures (CATS)

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.

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


Applications

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


Features

  • Rigorous computation of surface currents
  • Surface coordinates 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

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.
