摘要
本文根据红外遥感原理,探讨渔用红外遥感传感器参数设计的依据,并得出结论;渔用红外扫描仪工作波段宜采用8—14μm;为了达到渔用0.1℃的温度灵敏度要求,可采用Ge:Hg光电探测元件,并用液化气体的冷却设备,以降低噪声;传感器在获得0.1℃的温度分辨率下,具有几十米甚至上百米的空间分辨率即能达到渔用的最低要求。
The water temperature is one of the most important environmenta factors of marine fishes. The temperature image obtainted from the sea—surface by the marine infra—remote sensing can provide information for fishing, This paper, based on the principle of infra—remo te sensing, deals with the parameter designing basis of the infra—remote sensing transducerS for fishing, and draws tle fcllcwing Conclusion: Working wave—band 8—14μm of the infra—scanner is suitable for the use of fishing);In order to meet the demands of the sensitivity of the temperature 0.1℃ in the use for fishing, Ge:Hg photoelectric detector and liquidated gas for cooling the appratus shcud be used to reduce noise;In the case of obtaining resolution of temperature 0.1℃the tra nsducer has the spatial resolution of more than ten meters even more than one hundred meters, namely, the transducer can meet the lowest needs for fishing.
