| Abstract: |
| Operating distance, which is mostly influenced by a few factors such as atmosphere, background and so on, is one of the main capabilities of IR system. Considering the shortage of traditional calculating formula, and based on synthetical analysis, the optimal calculation method was presented. Exact calculation of atmospheric attenuation was carried out for the first time and the new method was validated by experiment. The results showed that the new method has better precision, which can be used in performance prediction and overall design of IR system. |
