| 中文摘要: |
| 作用距离是红外系统核心性能指标之一， 受大气、 背景等多方面因素的影响。针对传统作用距离计算方法存在的局限， 综合考虑多个影响因素， 提出了一种优化计算方法， 首次精确计算了作用距离与实际距离之差的大气衰减值， 并对计算方法进行了验证。结果表明,优化计算方法具有较好的计算精度， 可用于红外系统性能预测和整体设计。 |
| 英文摘要: |
| 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. |
