This invention provides a calibration system and radar for delay calibration of TDC timing channels. The calibration system sends periodic signals to each carry-chain timing channel via a clock generator, enabling each carry-chain timing channel to monitor the transition edge of the same periodic signal. The calibration module subtracts the trigger times of the transition edges of the same periodic signal obtained by each pair of carry-chain timing channels to obtain the delay time between each pair of carry-chain timing channels. Thus, when calculating the time difference between the output times of any two carry-chain timing channels, the system calibrates the time difference based on the delay time, improving the accuracy of the time difference output by the carry-chain timing channels and thereby improving the radar monitoring accuracy.
