Abstract

Lidar has been widely used in Autonomous driving and robot. To accelerate the research and development of Lidar technology, test and validation is of vital important. In this work, a target simulator for Lidar is designed and demonstrated. Mainly two functions are realized including distance and environmental attenuation simulation. For the distance simulation, the time-of-flight (ToR) method is introduced and a cascaded optical delay module is designed to generate an optical delay from 2ns to up to 4μs with a step as low as 40ps, corresponding to the simulated distance from nearly zero to more than 500m. For the environmental attenuation simulation, the various factors that may influence the backscattered power are analyzed and the relationship between the factors and loss is established. A commercial Lidar is tested using the target simulator and the result shows good consistence with the result obtained using reflector panel. Also the main challenge and further solution is discussed for the optimization of the target simulator.
