Remcom has developed a software product for automotive radar design and placement, a targeted niche application for sensor designers at automotive manufacturers and their Tier 1 suppliers. WaveFarer® is a highly accurate simulator for drive scenario modeling, allowing engineers to set up virtual track testing and use the results to refine their designs early in the development process. This makes physical testing more successful, as the prototypes more closely meet requirements. WaveFarer is a more efficient simulation tool for teams focusing on target detection signal processing and sensor placement, because it was created specifically for simulating radar sensors. Drive scenarios and sensor locations can be iterated in WaveFarer, reducing the cost and time to build prototypes and improving sensor placement and the resulting performance.

To predict the scattered returns from a drive test, WaveFarer uses ray-tracing algorithms adapted for radar. Employing near-field propagation and scattering methods, the raw radar returns from target objects are computed, including the multipath interactions from ground reflections and other structures. The software supports the global automotive bands to frequencies above 100 GHz.

WaveFarer is integrated into Remcom’s electromagnetic - simulation platform, working seamlessly with XFdtd® EM Simulation Software. This streamlines radar returns incorporating high fidelity radar antenna and sensor simulations to be calculated in end-to-end drive scenarios. A common user interface between XFdtd and WaveFarer simplifies the design process, with CAD import, geometry editing, visualization, definitions and results analysis sharing similar controls and a unified workflow. This consistent user experience will help RF engineers who need full-wave simulation for antenna design and ray-tracing analysis for drive test modeling.
