Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Frequency-modulated continuous-wave (FMCW) light detection and ranging (LiDAR) has the advantages of noncontact measurements, resistance to ambient light interference, high resolution, and the ability to simultaneously determine speed and distance information. In recent years, it has been widely used in various fields, including aerospace, precision manufacturing, and autonomous driving. The ranging performance of FMCW LiDAR significantly depends on the sweep linearity of its light source, which is typically influenced by several factors, such as uneven stress stretching, temperature variations, and circuit noise. These factors decrease the ranging resolution and accuracy. The influence of light source nonlinearity in FMCW LiDAR is analyzed theoretically, and research progress in different types of nonlinearity correction techniques is presented. The characteristics, advantages, and disadvantages of each method are summarized to provide a reference for future research.
