| Abstract: | For the problem of De ambiguous in the measurement of range by phases under stagger relation of frequency difference, we give the condition of correctly De ambiguous under relatively prime stagger relation and actual noisy circumstance and the proof. Then we discussed fast algorithm for De ambiguous problem, theoretical ranging error when ranged by stagger frequency difference, and the SNR value that assure De ambiguous reliably. |

| Keywords: | range measurement by phases stagger maximum unambiguous range |
