Dual-polarization joint signal noise processing method and noise processing device

Abstract

The invention relates to the technical field of noise processing, in particular to a dual-polarization joint signal noise processing method and a noise processing device. According to the method, the noise information carried in the discrete spectrum characteristic values of the X and Y polarization states and the correlation coefficient between the noise information and the discrete spectrum coefficient in the X polarization state are used for compensating the discrete spectrum coefficient noise in the X polarization state; and compensating the noise of the discrete spectral coefficient in the Y polarization state by using the noise information carried in the discrete spectral characteristic values of the X and Y polarization states and the correlation coefficient between the noise information and the discrete spectral coefficient in the Y polarization state. According to the method, when the discrete spectral coefficient noise in the X and Y polarization states is compensated, the characteristic value noise in the X and Y polarization states is utilized at the same time, and more known noise information is introduced, so that the discrete spectral coefficient noise compensation in the X and Y polarization states is better realized. 本发明涉及噪声处理技术领域，具体是涉及双偏振联合信号噪声处理方法和噪声处理装置。本发明用X、Y偏振态离散谱特征值中携带的噪声信息及其与X偏振态上的离散谱系数之间的相关系数补偿X偏振态上的离散谱系数噪声，同样用X、Y偏振态离散谱特征值中携带的噪声信息及其与Y偏振态上的离散谱系数之间的相关系数补偿Y偏振态上的离散谱系数噪声。本发明补偿X和Y偏振态上的离散谱系数噪声时，同时利用了X和Y偏振态上的特征值噪声，引入了更多的已知噪声信息，从而更好地实现对X和Y偏振态上的离散谱系数噪声补偿。
