摘要： 剖析了脉冲对技术进行流速测量的方法,利用该算法可以很好地提取出淹没在白噪声下的频偏信息。给出了评判参数C_SNR,论证了C_SNR与SNR之间的必然关系。海量实验数据证明,对应的数据是鲁棒的。

Abstract: Pulse-to-pulse algorithm is discussed,with which frequency offset estimate can be obtained easily.The C_SNR is raised and the certain relation between them is demonstrated.The results indicate that frequency offset can be obtained robustly.
