Lidar Target Simulator for Sensor Test and Validation

09 June 2023 - Keysight Technologies expanded its portfolio of autonomous driving validation test solutions with the E8717A Lidar Target Simulator (LTS), which enables automakers and lidar sensor makers to test and validate lidar sensors for autonomous vehicles (AV). The Keysight LTS solution allows to simulate test targets at defined distance and reflectivity with a compact and standardized bench setup.

Initially developed for use in meteorology and topography, lidar is now being adopted as an automotive sensing technology that enables AVs to "see" and safely navigate through complex driving scenarios. As with radar-based systems, lidar sensor makers must ensure lidar systems quickly and reliably detect objects, enabling advanced driver assistance systems (ADAS) to work correctly before they are commercially deployed. To properly test sensors, designers currently need large floor spaces and use traditional target boards. In addition, the industry is also faced with reducing sensor cost and scaling to mass production.

The Keysight LTS solution addresses these challenges by simulating test targets at defined distance and reflectivity with a compact and standardized bench setup. This solution is designed to simplify and accelerate the testing, validation, and production of automotive lidar sensors through standardization and automation.

The following benefits are provided by the Keysight LTS:

• Small footprint covering large distances – Compact bench setup saves test floor space by simulating target distances from 3 meters to 300 meters and simulating surface reflectivity from 10% to 94%.
• Insightful analytics improve sensor design and performance – Powerful testing software generates insightful analytics by sweeping target distance and reflectivity, enabling design and performance improvements.
• Automated software accelerates testing – The LTS test setup is fully automated using a cobot and powered by Keysight PathWave Test Executive for Manufacturing for test automation. While the cobot provides precise device movement for field of view testing, the automation software accelerates testing and throughput to support volume production.

Thomas Goetzl, Vice President and General Manager for Keysight's Automotive & Energy Solutions, said: "Keysight sees an exciting role that lidar can play in enabling autonomous vehicles to navigate more accurately with an extra sensor that complements cameras and radars. With the market's first cobot-assisted lidar target simulator with variable distance and reflectivity simulation, we are ready to support a volume roll out of lidar with a scalable manufacturing test solution."

Keysight will demonstrate the capabilities of the E8717A Lidar Target Simulator at Automotive Testing Expo Europe 2023 in Stuttgart, Germany, Hall 10 Booth #1332, June 13-15, 2023.
