Abstract

A lidar system comprises a photodetector circuit and a signal processing circuit. The photodetector circuit comprises an array of pixels for sensing incident light. The signal processing circuit processes a signal representative of the sensed incident light to detect a reflection of a laser pulse from a target within a field of view. The signal processing circuit can comprise a matched filter corresponding to a retro-reflective target that is tuned to a reflected pulse shape that exhibits a vertical clipping relative to a transmitted pulse shape for the laser pulse that is indicative of the retro-reflective target, and wherein the signal processing circuit determines a retro-reflector status for the target based how the matched filter responds to the applied signal.
