RASES / Radar Cross Section Computation

-A +A

RASES is a high-frequency electromagnetic simulation software which is capable of calculating Radar Cross Section (RCS) of complex targets. The computation methods that are implemented within the software are Physical Optics (PO), Shooting and Bouncing Ray (SBR) and Physical Theory of Diffraction (PTD).

  • RADAR CROSS SECTION COMPUTATION

Monostatic and bistatic RCS computations can be performed for different frequencies, materials, incidence and observation angles within the simulation environment. Statistical information of the evaluated RCS values can also be investigated. The variation of the RCS values of a target due to any specific maneuver can be analyzed. RASES provides reliable RCS results which have been verified by analytical solutions, numerical methods and experimental results.

  • EVALUATION OF RANGE PROFILES AND ISAR IMAGES

Within the RASES software, 1-D (Range Profile), 2-D and 3-D ISAR images of the targets can be constructed by using the estimated RCS values. By using Inverse Synthetic Aperture Radar (ISAR) images, dominant scattering regions on a platform could be determined.

  • DETERMINATION OF SCATTERING CENTERS

Positions and amplitudes of the scattering centers that can be extracted from 1-D, 2-D and 3-D ISAR images are of high importance for the RCS reduction studies of the targets. Extraction of the scattering centers is performed via the CLEAN algorithm.

  • DESIGN PROPOSALS FOR RCS REDUCTION

The RCS value of a platform can be reduced via structural modifications on a platform or the usage of radar absorbing materials (RAM). By using the built-in coating material types of RASES and by including the electrical specifications of new material types in the material library of RASES, the effects of the RAM application can be observed in terms of RCS variations. The structural modifications that can be performed by using several commercial CAD software, can also be input to RASES in order to investigate and design platforms with low RCS values.
