Atmospheric path radiance is the key factor in the accuracy of objective radiation measurement. In the traditional radiation character measurements
it is compared with the results of MODTRAN and measurement in experiment. It is revealed that the accuracy of software is 7.8%
under the help of the atmospheric observation equipment
and the formula is 4.9%
MODTRAN and other software likewise
which could demonstrate the validity of the pproximate calculation formula in close range and horizontal direction. In this article
the indeterminacy rate could be around 10~20%
in the process of deducing and experiment
it is highly restricts the measurement accuracy of objective radiation. For this reason
the validity of the approximate calculation formula in close range and horizontal direction is fully proved
it is quite significant to develop the study of measure and calculation in path radiance. The approximate calculation formula for path radiance in close range and horizontal direction is expressed in this article
which supply a new method in approximate calculation of path radiance for objective radiation measurement. (2013) Trans Tech Publications

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.
