Matematyka Fundacje of LIDAR Velocity Estimation

LIDAR systemy emit laser pulses and measure thee time takes for thee light to reflect back from objects. By analyzing the e change in position of thee reflect signals over time, thee velocity of af an object can be calculated. The cre mathetical concept involves thee Doppler effect and time -of- flight meverements.

Te Doppler shift in thee frequency of thee reflect te laser signals provides information thee relative velocity between thee sensor andthee object. The basic formula relates thee observed frequency too thee velocity:
