WaveFarer® is a high fidelity radar simulator that accounts for multipath and scattering from structures and vehicles in the immediate environment of a radar system as well as key atmospheric and scattering effects for frequencies up to and beyond 100 GHz.

Applications include simulation of automotive drive scenarios, indoor sensors, and far field radar cross section (RCS).

WaveFarer Radar Simulation Software 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 multi-path interactions with ground reflections, using ray-tracing algorithms and physics-based calculations.

Targeted ray casting Efficiently produce high-fidelity returns from a target.

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

Dynamic scenario Apply movement to radar sensors, target vehicles, and other scatterers.

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.

WaveFarer 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.

Automotive Radar Simulation technology has advanced to meet more stringent design requirements for 24 GHz and 77 GHz automotive radar sensors including blind spot detection (BSD) and lane change assistance (LCA). Remcom offers an integrated approach from sensor design to drive test scenarios.

Radar and Scattering Remcom’s software products are important tools for analyses including Radar Cross Section (RCS) computation, radar antenna design, and scattering applications.
