AbstractThis paper summarize range error caused by instability of transmission characteristics and change of signal frequency and amplitude. On the basis of transmission system's modulation-demodulation combined characteristic, amplitude-frequency characteristics even symmetry, phase-frequency characteristics odd symmetry, phase orthogonality of demodulator, author analyses influence of factors on range accuracy. And formulas of phase of ranging tone are derived. Using these formulas, the many factors having influence on drift range error may be calculated, and range accuracy can be improved. Above conclusion has been testfied and applied in TT&C system for years.
