A comparison study on temperature measurement precision between middlewave 3-5m and longwave 8-12m measuring thermal imaging systems has been conducted. The study was limited to systems working in indoor conditions and the target's temperature is in the range of 270K900K. First  the Disturb Resisting Function (DRF) of infrared systems is deduced. On the base of DRF curve  we find that the middlewave infrared system get the smaller influences under the same size disturb compared with the longwave system. A theory of the influence of target's physical characteristic and measurement conditions on the accuracy of temperature measurements has been developed. On the basis of the developed formulas an analysis of the influence of signal disturbances (because of incorrectly assumed emissivity  limited transmittance of the atmosphere  radiation reflected by the object and shift of optics radiation) on the accuracy of temperature measurement has been made. It has been found that the middlewave systems in typical temperature range offer generally better accuracy in temperature measurement than the longwave ones do. 2012 IEEE.

Infrared radiation signature measurement of targets is one of important ways for target signature acquirement and target recognition. When measuring the infrared signature of a target in the atmosphere  molecules and aerosol particles in the atmosphere would attenuate the infrared radiation from the target  and at the same time  the air path radiation would be added to the target radiation. Therefore  in order to obtain the intrinsic infrared radiation of the target  it is necessary to perform atmospheric correction in the process of target radiation inversion. A model for target radiation measurement and inversion was established  and precision analysis on the model was given. A longwave infrared camera was used to perform infrared signature measurement experiment on an ISDC extended-area blackbody. Based on atmospheric parameters  the atmospheric transmittance and the air path radiation between the blackbody target and the camera were calculated by using the MODTRAN software  for use in atmospheric correction in the target radiation inversion process. The experimental results showed that radiation inversion precisions were about 7.3%9.3%. Additionally  inversion precision will improve as target temperature rises. 2010 IEEE.
