Keysight Technologies, which provides advanced design and validation solutions, has announced the Radar Scene Emulator, which lets automakers lab test complex, real-world driving scenarios. The company said it will demonstrate the emulator at CES 2022 (Booth #4169) in Las Vegas in January.
The company said full-scene emulation in the lab is critical to developing the robust radar sensors and algorithms needed to realize advanced driver assistance systems (ADAS) and autonomous driving capabilities. The full-scene emulator combines hundreds of miniature radio frequency (RF) front ends into a scalable emulation screen, representing up to 512 objects and distances as close as 1.5 meters, Keysight said.
The emulator includes patented technology that shifts from an approach centered on object detection via target simulation to traffic scene emulation, offering automotive OEMs the following benefits, Keystone said:
- Seeing the big picture: The emulator allows radar sensors to see more with a wider, continuous field of view, supporting both near and far targets. This eliminates gaps in a radar’s vision, enabling improved training of algorithms to detect and differentiate multiple objects in dense, complex scenes.
- Testing real-world complexity: The company said testing radar sensors against a limited number of targets provides an incomplete view of driving scenarios, and masks the complexity of the real world. The Radar Scene Emulator lets OEMS emulate real-world driving scenes in the lab with variations of traffic density, speed, distance and total number of targets. The company said testing can be completed early for common to corner case scenarios while also minimizing risk.
- Accelerate learning: The system provides a deterministic real-world environment for lab testing complex scenes that today can only be tested on the road. This approach lets OEMs significantly accelerate ADAS/AD algorithm learning by testing scenarios earlier with complex repeatable high-density scenes, with objects stationary or in motion, varying environmental characteristics, while eliminating inefficiencies from manual or robotic automation.
“Keysight’s Radar Scene Emulator offers automotive OEMs a breakthrough solution that will bring the road to the lab through full scene rendering,” said Thomas Goetzl, vice president and general manager for Keysight’s automotive and energy solutions business unit. “The vision of fully autonomous vehicles is rapidly approaching, and we’re thrilled to be accelerating this vision into a reality.”
The emulator is part of Keysight’s Autonomous Drive Emulation (ADE) platform, created through a multi-year collaboration between Keysight, IPG Automotive and Nordsys. It exercises ADAS and AD software through the rendering of predefined use cases that apply time-synchronized inputs to the actual sensors and subsystems in a car, such as a global navigation satellite system (GNSS), vehicle-to-everything (V2X), cameras and radar. Automotive OEMs can integrate the platform with commercial 3D modeling, hardware-in-the-loop (HIL) systems and existing test and simulation environments.
“Automotive companies understand the complexity involved with testing autonomous driving algorithms and the quality issues that can result if that testing falls short,” said Cheryl Ajluni, director of automotive solutions marketing at Keysight. “Keysight’s new Radar Scene Emulator, with its unmatched level of resolution, represents a significant leap forward for ADAS/autonomous driving developers who value safety first.”
