This example details the setup and execution of RCS calculations using XGtd’s X3D PO MEC model and compares the predictions to those made using XFdtd.
This example analyzes the coupling between four circular patch antennas mounted on the sides of a Boeing 757. The antennas transmit and receive at a frequency of 2.4 GHz. Coupling between each antenna is characterized using XGtd’s S-Parameter output, which can be displayed in the user interface or exported to a v1.1 Touchstone file.
A comparison of XGtd and FDTD calculated antenna gain for a half-wave dipole inside a corner reflector.
This example considers the far zone antenna gain patterns from a 0.125 m monopole antenna situated on top of a metal box.
Wind turbines located near a radar installation can significantly interfere with the ability of the radar to operate properly. Remcom has performed a number of research efforts into the impact that wind turbines and wind farms have on radar returns for Air Traffic Control (ATC) radar, early warning radar, weather radar, and instrumentation radar. Highlights of some of these effects and relevant samples and white papers are provided in this brief overview.
Successful integration of an antenna onto a vehicle platform poses many challenges. This paper provides a variety of examples of how modeling and simulation can be used to analyze antenna performance, identify problems, and evaluate potential solutions.
Wind turbines located near radar installations can significantly interfere with a radar’s ability to detect its intended targets. Remcom’s XGtd software is a high frequency solver capable of calculating the radar cross section of electrically large objects. In this paper, interference from wind turbines is predicted using XGtd simulations.
This paper presents the major components of the “Virtual BAF” simulation model as well as a few examples of its use in preliminary test design and setup.
This short animation shows predicted RCS from an air traffic control radar with an aircraft flying over a wind farm, before and after the static ground clutter (returns from terrain) are filtered out.
Remcom’s XGtd can simulate the propagation paths of fields interacting with two wind turbines in close proximity. XGtd then generates a movie that shows the directions and magnitudes of the strongest propagation paths, including multipath occurring between the turbines.
Using the pre-loaded scripting library in XFdtd, this video demonstrates simulation of a helical antenna, which is then imported into XGtd for analysis on a satellite. See how XFdtd’s scripting language helps to quickly automate advanced modeling tasks. After the 3D far field pattern is imported into XGtd, the video shows how the software calculates the interaction of the antenna with an electrically large object -- in this case a satellite.
