Abstract
A method of performing ranging and detection with an array lidar system and the array lidar system include a first illuminator to transmit a first pseudorandom binary sequence of pulses, the first pseudorandom sequence of pulses resulting in first reflections, and a second illuminator to transmit a second pseudorandom sequence of pulses, the second pseudorandom sequence of pulses being transmitted at least partly concurrently with transmission of the first pseudorandom sequence of pulses, the second pseudorandom sequence of pulses resulting in second reflections. A receiver receives the first reflections and the second reflections and associates the first reflections with the first illuminator based on a result of correlating the first reflections with the first pseudorandom sequence of pulses and a result of correlating the first reflections with the second pseudorandom sequence of pulses, the receiver includes an optical detector array and a processor.
