Abstract

Discrete sampling is one of the important characteristics of thermal imaging systems and has an important effect on the target acquisition performance. Based on the study of discrete sampling theory, several discrete sampling evaluation methods are analyzed, and the aliasing caused by under-sampling is considered as a noise of thermal imaging systems. The aliasing noise is introduced into MRTD model with system noise. MRTD model with aliasing noise is deduced, and its validity is verified by simulation experiments. MRTD model with aliasing noise is introduced into MRTD channel width model. It is future work that the impact of discrete sampling on the general performance of thermal imaging systems will be researched by MRTD channel width model.
