This study describes the development of a prototype bi-spectral microbolometer sensor system designed explicitly for radiometric measurement and characterization of wildfire mid- and long-wave infrared radiances. The system is tested experimentally over moderate-scale experimental burns coincident with FLIR reference imagery. Statistical comparison of the fire radiative power (FRP; W) retrievals suggest that this novel system is highly reliable for use in collecting radiometric measurements of biomass burning. As such, this study provides clear experimental evidence that mid-wave infrared microbolometers are capable of collecting FRP measurements. Furthermore, given the low resource nature of this detector type, it presents a suitable option for monitoring wildfire behaviour from low resource platforms such as unmanned aerial vehicles (UAVs) or nanosats.
本研究描述了一种原型双光谱微测辐射热计传感器系统的开发，该系统专门用于辐射测量和野火中波和长波红外辐射亮度的特性描述。该系统在与 FLIR 参考图像同时进行的中等规模实验性燃烧中进行了实验测试。对火灾辐射功率 (FRP; W) 反演结果的统计比较表明，该新型系统非常可靠，可用于收集生物质燃烧的辐射测量值。因此，本研究提供了明确的实验证据，证明中波红外微测辐射热计能够收集 FRP 测量值。此外，鉴于这种探测器类型的资源消耗低，它为从无人机 (UAV) 或纳米卫星等低资源平台监测野火行为提供了一个合适的选择。
