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.

The main methods to measure the target IR features are the following two ways: test and then measurement
or theoretical and simulation calculation. The former is direct measurement so the results are more accurate but the test is costly and complicated
so that it is limited in the application. Theoretical and simulation calculation are widely used in the target IR radiation calibration. Here we give the basic configuration of the calibration platform for measuring the IR radiation of the large area low temperature blackbody source
and discuss the calibration flowchart and key technologies for atmospheric transmission correction. The dynamic data are analyzed in real time to determine the IR radiation features in the data fusion subsystem
and the experimental results show that the calibration method is feasible and practical. 2010 IEEE.
