XGtd Features

X3D RCS Model is a GPU-enabled multi-threaded 3D propagation model with no restrictions on geometry shape or transmitter/receiver height. This accurate model includes reflections and diffractions along with atmospheric absorption. Supports frequencies up to 100 GHz.

Full 3D Model The Full 3D propagation model predicts the paths by which energy travels from the transmitting antenna to the receiving location. This model would

Graphical User Interface XGtd's modular 64-bit GUI makes it easy to import objects to set up projects for various electrical large platforms. Users can simulate co-site analysis, antenna placement, radar cross section, and anechoic chambers.

Feature Import Support for KMZ, COLLADA, STL and DXF formats for object import.

Large Platform Simulations XGtd’s methods are less impacted by the platform’s electrical size than full wave techniques, supporting larger structures and higher frequencies.

Ray Path Visualization Display ray paths for far zone antenna gain, RCS calculations, or antenna coupling. Rays are colored according to strength, allowing users to identify scattering features.

XFdtd Compatibility for Higher Fidelity Antenna Patterns Calculate antenna radiation patterns for complex antenna designs using XFdtd. Import into XGtd to determine effects of placement on electrically-large platforms.

Antennas Import simulated antennas from XFdtd or create textbook antennas for use as transmitters and receivers.

Materials Electrical properties of the scene can be defined down to the facet level. An installed database of materials includes metal and absorbers.

Outputs Users have quick access to outputs such as direction-of-arrival, complex impulse response, E-field vs. time, and E-field vs. frequency for each transmitter-receiver link. These ASCII-based files can be plotted in the tool or easily post-processed externally. S-parameters are exported to touchstone.
