| 摘 要： | 基于红外成像系统作用距离估算最小可分辨温差（MRTD）方法建立了红外偏振成像系统作用距离模型，分析了背景杂波影响下红外偏振成像系统作用距离。通过仿真发现，红外偏振成像系统作用距离是由目标/背景红外偏振特性、大气传输过程和观察方式等众多因素共同决定的，背景杂乱程度大幅影响红外偏振成像系统作用距离，偏振成像模式与强度成像模式依据应用条件的不同具有不同的优势。

| Abstract: | The operating range model of the infrared polarization imaging system was established based on the minimum resolvable temperature difference(MRTD) between the target and the background. The impact of the background clutter on the operating range was also analyzed. Simulation results show that the operating range is concurrently dependent on the target/background polarization characteristics, atmospheric transmission and the observation geometry. Among these factors, the background clutter greatly affects the operating range of infrared polarization imaging system. Besides, polarization imaging mode and intensity imaging mode may have different advantages compared with each other under different imaging conditions. |
