High-Frequency Duct Scattering (DUCTSCAT)

Overview

DUCTSCAT (high-frequency duct scattering) is a computer code designed for evaluating the radar cross section performance of duct geometries with optional material treatments.

Applications

DUCTSCAT has been used to perform radar cross section signature analysis on various aircrafts and ships that have duct shaped geometries.

Benefits

• DUCTSCAT predicts radar signature for arbitrary and complex ducts with optional material treatments. The material type is described in terms of its frequency and incident angle reflectivity.
• DUCTSCAT automatically interpolates between angle entries in the material tables as it performs the ray bounce calculations.

Product Features

• Computation of two orthogonal polarizations
• Contributions only from duct interior
• Arbitrary shape
• Complex Y-shaped ducts with multiple entrance and/or exit apertures
• Perfect exit aperture
• Material treatments
• Material type in terms of frequency and incident angle dependent reflectivity
• Automatic interpolation between angle entries
