Targeted Ray Casting

Efficiently produce high-fidelity returns from a target.

Ray-tracing algorithms shoot rays into a scene from each transmitter. WaveFarer provides a unique solution that launches a packet of rays at each scattering object.  This ensures that the entire surface visible to a transmitter is illuminated with rays.  The alternative traditional approach launches rays at a specified angular spacing, which is less effective in achieving full illumination of finely-detailed target surfaces, even when very high ray densities are used.  

For automotive radar, where vehicles are in motion, WaveFarer’s approach improves both accuracy and efficiency by ensuring the target is fully illuminated at any distance from the transmitter.  With a traditional fixed ray spacing approach, the angular resolution must be decreased as the target moves further away.  This makes it impractical to scatter off detailed surfaces at longer distances and is also more difficult to define for a dynamic scenario when target ranges vary with time.

Targets are fully illuminated with rays independent of distance.
