Analysis and Simulation of Intensity Correlation Imaging Noise Towards High-Orbit Satellite
Intensity correlation imaging method can obtain high-resolution image by low-precision equipment on ground, which is a developing high-orbit satellite imaging method, but the method has some disadvantages such as low signal to noise ratio.In order to make clear the main noise source when observing high-orbit satellite by this method, analysis and simulations for the noise of intensity correlation imaging has been done.In this paper the theory and history of intensity correlation is described;the deviation and noise of intensity correlation imaging is analyzed according to the characteristic of high-orbit satellite;simulation about shot noise and partial coherence deviation has been done on semi-classical model.Analysis shows that the area of light-collecting mirrors affected the noise and deviation in intensity correlation imaging, the area should be optimized according to the diameter and brightness of satellite.
