| Abstract: | In this paper,the noise of staring thermal imaging system is discussed.Firstly,the differences between the first and second-generation thermal image system are stated and analyzed.Secondly,the 3-D noise model is introduced,which is used to analyze the noise of the staring image system.The noise of the system is divided into 7 components,and every component is analyzed in detail,the result of the experiment is put forward.At last,the affection of every noise component,which can affect the MRTD,is discussed. |
