Applications

WaveFarer is designed to support all applications relevant for simulation and analysis of a radar system. For automotive radar, this includes evaluating radar sensor placement and target returns within a simulated drive scenario environment. For surveillance radar applications, this includes analysis of target radar cross section (RCS) and the impact of materials on results. For a variety of other radar and sensor applications, WaveFarer can be used to determine how the placement of a sensor and the presence of various nearby structures might affect the radar returns.

WaveFarer Features

WaveFarer’s features enable fast and accurate analysis of scenarios with radars in close proximity to structures, targets, and other features in a simulated environment. Key features include the following:

Near field propagation method Calculate scattering off target surfaces, including multipath interactions with ground reflections, using ray-tracing algorithms and physics-based calculations.

Targeted ray casting Efficiently produce high fidelity returns by fully-illuminating targets.

Diffuse Scattering Calculate contribution of scattering from rough surfaces to radar clutter.

Dynamic scenario Apply movement to radar sensors, target vehicles, and other scatterers in your drive test simulations.

User defined antennas Import measured or simulated radiation patterns.

Scripts for chirp waveforms and range-Doppler Use WaveFarer scripts and utilities to simulate chirp waveforms, and post-process results to provide range-Doppler and other outputs.

Shared platform with XFdtd Integrated solution promotes productivity.

Scalable Modeling of Human Blockage at Millimeter-Wave: A Comparative Analysis of Knife-Edge Diffraction, the Uniform Theory of Diffraction, and Physical Optics Against 60 GHz Channel Measurements

Human blockage at millimeter-wave frequencies is most commonly modeled through Knife-Edge Diffraction (KED) from the edges of the body shaped as a vertical strip. Although extensively validated in controlled laboratory experiments, the model does not scale to realistic 3D scenarios with many, randomly oriented bodies, on which multipath signals can be incident from any direction, not just normal to the strip. To address this, in this article we investigate computational electromagnetic methods based on raytracing.

Using WaveFarer Radar Simulation Software to Predict How Waves Propagate in an Indoor Environment

Using WaveFarer's included scripts, users can leverage Remcom's XGtd path viewer to generate ray path animations. This clip demonstrates the capability by showing backscatter in an indoor scenario, visualizing how waves diffract through doorways and penetrate walls.

Diffuse Scattering in WaveFarer

WaveFarer’s diffuse scattering model increases the fidelity of the simulation by revealing how paths interact with rough surfaces, leading to additional clutter in radar returns.
