Abstract
Method and system for performing ranging operation are provided. In one example, a transmitter is configured to transmit a first signal having a first signal level and a second signal having a second signal level, the second signal being transmitted after the first signal, the first signal and the second signal being separated by a time gap configured based on a minimum distance of a range of distances to be measured by the LiDAR module. The first signal level and the second signal level are configured based on the range of distances to be measured by the LiDAR module, a range of levels of reflectivity of a target object to be detected by the LiDAR module, and a dynamic range of a receiver circuit to receive the first signal and the second signal. Ranging operation can be performed based on the time-of-flight of at least one of the first signal or the second signal.
