摘要: |
针对相位测距雷达在采用参差频差关系测距时的解距离模糊问题,本文给出了在两两互素参差关系及实际噪扰条件下正确解模糊的条件及其证明,并且讨论了解模糊的快速算法、采用参差频差关系测距时的理论测距误差以及为保证可靠解模糊所需的信噪比问题。 |

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 |
