1.Under the Swerling II assumption, the analytic expressions of false-alarm probability (Pfa), detection probability (Pd) and Average Decision Threshold (ADT) of this detector are derived, its detection performances in homogeneous background and in strong interfering targets environment are analyzed, and compared with that of OS-, GOSGO-CFARs.
我们推导出了该检测器在Swerling Ⅱ型目标假设下的虚警概率(P_(fa))、检测概率(Pd)和度量平均判决门限(ADT)解析表达式。 分析了它在均匀背景和强干扰环境中的检测性能。收藏指正
2.For higher extraction efficiency and low threshold operation to the quasi-three level laser system, the Tm,Ho∶YLF crystal is cooled by liquid nitrogen reserved in a small detector type dewar, and works at the temperature of 77 K.
为降低准三能级 系统激光器阈值,提高激光脉冲能量抽取效率,Tm,Ho∶YLF晶体采用液氮制冷方式,工作在77K温度条件下。收藏指正
3.GR 200A and MCP N are the same kind of LiF(Mg, Cu, P) chip detectors. The main dosimetric characteristics of two LiF (Mg, Cu, P) chip TLDs (GR 200A made in Solid Dosimetric Detector & Method Laboratory, Beijing, and MCP N made in Poland) are compared, including glow curve structure, TL sensitivity, anti moisture, reproducibility, background, detection threshold and photosensitivity.
GR?200A（本实验室产品）与MCP?N（波兰产品）均为LiF（Mg，Cu，P）片状探测器，现将GR?200A和MCP?N在发光曲线、灵敏度、重复使用、抗潮湿性能、本底、探测阈、光敏等性能进行平行对比实验，其中GR－200A的灵敏度为MCP?N的1?6倍；收藏指正
