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.

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.
