PinnedLiDAR vs RADARLiDAR vs RADAR is an interesting topic, especially after recently in Feb Tesla has announced to remove RADAR mainly because of accuracy and signl/noise issue. Tesla CEO also announced not to use LiDAR because of its high cost. https://www.caranddriver.com/news/a39250157/tesla-no-radar-sensor-model-s-model-x/ Regarding RADAR, Musk shared in June of last year after Tesla…Lidar9 min readLidar9 min read
PinnedFMCW LiDAR vs. ToF LiDARThis article compares Frequency Modulated Continuous Wave (FMCW) and Time of Flight (ToF) for LiDAR. In summary, FMCW is better in longer term but ToF is still better now. What are FMCW and ToF? Lidar can take on several different modalities, which can be classified by their dependence on incoherence or coherence of the laser…Lidar6 min readLidar6 min read
