1. A method of determining a time-of-flight of a device under test, comprising the steps of:

  • detecting a returning signal returning from the device under test in response to a probing signal comprising a sequence of pulses according to a first code sequence, and deriving a second code sequence from the detected returning signal, determining a correlation function by correlating the first code sequence and the second code sequence and identifying a main peak of the correlation function, and determining a time position of the main peak.
