Abstract:
    This invention discloses one Fourier change by use of guide frequency character to get the signal frequency bias estimation values and for frequency two time plug values through estimation values on bias frequency to improve estimation accuracy and compensation method. This invention method overcomes the current test method problems of two small line range of delta phi is approximately equal to sin(delta phi).
