1. A time correction device, comprising:
a first time measurement component configured to measure a receiving time of a valid signal;
a correction component configured to collect correction information for correcting the receiving time of the valid signal, the correction information including an amplitude and a duration of a target portion of the valid signal; and
a processing device configured to determine a corrected receiving time of the valid signal by correcting the receiving time of the valid signal based on the correction information.
