Abstract A new 3D noise analysis method is introduced on the basis of analyzing the radiometric performance and noise of optical satellite image. The imaging noise can be divided into seven parts according to temporal and horizontal, vertical dimensions. The paper analyses the content of 3D noise. Several satellite images are used to validate the method. This method provides a feasible way to evaluate the imaging quality and to evaluate the methods of improving image quality.
