Full-waveform pulsed LiDAR dataset

A dataset comprised of full-waveform (periodically sampled) pulses emulating LiDAR signals is provided. The waveforms were captured at a sampling rate of 20 Gsample/s and over a dynamic range of 45 dB. A simple Python notebook is also given, showing how to properly load the waveforms and capture parameters from the stored .mat file.

The dataset was used to demonstrate a new time-frequency estimation method for pulsed LiDAR systems [1].

The dataset was also used to build efficient machine learning (ML) models capable of accurate and precise time-of-flight estimations [2].

For full details, please check the Experimental Setup in [1].
