XGtd: Far Zone Radiation And RCS For Electrically-Large Platforms

Source: Remcom, Inc.

XGtd®: High Frequency EM Propagation Software

XGtd is a ray-based electromagnetic analysis tool for assessing the effects of a vehicle or vessel on antenna radiation, predicting coupling between antennas, and predicting radar cross section (RCS).  It is ideally suited for applications with higher frequencies or very large platforms where the requirements of a full physics method may exceed available computational resources.

XGtd’s capabilities extend well beyond standard ray tracing codes, incorporating techniques including Geometric Optics (GO), the Uniform Theory of Diffraction (UTD), Physical Optics (PO), and the Method of Equivalent Currents (MEC). XGtd provides high-fidelity outputs tailored to its intended applications.

Computational methods include:

  • Ray tracing methods: Shooting and bouncing ray & image theory
  • E-field evaluations using UTD, GO, PO, and MEC
  • High-fidelity field predictions in shadow zones including creeping wave effects
  • Multipath calculations including reflections, transmissions, wedge diffractions, surface diffractions, and creeping waves

Applications:

  • Antenna Radiation from Platform-Mounted Antennas
  • Radar Cross Section (RCS)
  • Co-Site Analysis
  • Anechoic Chamber Simulation

Key Features:

  • X3D RCS Model
  • Full 3D Model
  • Graphical User Interface
