1. the method for the numeral of an accumulated phase that is used to produce echo signal, described method comprises:

  • The frequency of described echo signal is removed signal divided by divider ratio N to produce;

    Described divider ratio N is accumulated as accumulation integer phase place;

    Produce the numeral of the phase difference between the corresponding incident in described incident and the reference signal of being removed in the signal;

    AndMake up described accumulation integer phase place and described Digital Phase Difference, with the described numeral of the described accumulated phase that produces described echo signal.
