noise coefficient

Since the expanding of the frequency bandwidth is mainly within the effective one, the main energy spiking deconvolution can usually produce a satisfied result by taking a very small white noise coefficient even in the case that more serious noises exit in the seismic record.

由于主能量反褶积主要是在地震波的有效频带范围内拓宽频谱，因此即使在噪音比较严重的的情况下仍可取很小的白噪系数而获得较好的反褶积效果。

It is assumed that random signals consist of white noise signal and non white noise signal. Non white noise coefficient is brought forward.

假定任意随机激励信号由白噪声与非白噪声信号组成，由此导出线性结构响应之间的相关函数由两部分组成，一部分与脉冲响应具有相同的数学形式，另一部分为其它形式。

This paper realized these two use, and conclusions could got by analyzing the time deviation, frequency deviation, frequency drift, Allan deviation and the noise coefficient. All these conclusions have proved that Kalman algorithm can achieve better results in these two ways.

论文实现了这两类运用，通过对滤波后时差、频差、频漂、Allan偏差以及噪声系数的分析，得出结论，证明Kalman滤波算法在这两类运用中都能取得较理想的结果。
