摘要

We present a range-gating delayed detection super-resolution imaging lidar with high accuracy based on the signal intensities of three consecutive delay samples.The system combines the range and signal intensity information from multi-pulse detections to calculate the pulse peak position under the assumption of a Gaussian pulse shape.Experimental results indicate that the proposed algorithm effectively calculates pulse peak position and exhibits excellent accuracy with super-resolution.Accuracy analysis shows that accuracy is best improved by enhancing signal-to-noise ratio,strategically selecting samples,reducing pulse width,and appropriately choosing the delayed periods between samples.
