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.
