评估飞机成像目标的红外隐身效果,对飞机红外隐身技术的发展、隐身反隐身作战具有重要的意义。提出了一种飞机成像目标红外隐身效果的评估方法:结合成像探测器工作原理,考虑图像处理各个阶段的算法特点,基于多种图像特征,制定出能反映背景影响和诱饵干扰影响的飞机成像目标红外隐身效果评估指标;通过建立红外成像探测器仿真模型,验证了所制定的评估指标的合理性;最后依据评估指标评估了采用不同隐身技术和施放诱饵干扰对飞机隐身效果的影响,得到了一些对飞机隐身和反隐身具有指导意义的结论。 相似文献

The article describes a model representation of radar probing data in form of a mixture of background and target samples, which is the sum of two random variables with very different parameters. For model development we research the behavior of the central moments of the distribution mix without assuming the distribution law form. An example it is described the detection of the signal at the output of compression system of chirp ionosonde. 相似文献

Assuming that visual responses are due to the action of particles on the membrane of the visual cells, the stochastic variability of the response should be a function of the number of particles producing it. Quantitative predictions can be made with the aid of a model proposed in previous articles. It is found that responses produced in visual cells of Limulus by absorption of a single photon have the stochastic properties which would be expected if the response to one photon were brought about by 25 particles. It is concluded from this that the processes leading to visual responses produce multiplication of particles. The effects of temperature and of metabolic poisons suggest that these processes are of chemical nature. 相似文献

A method for analyzing the luminescence spectra of semiconductors is suggested. The method is based on differentiation of
the spectra. The potentialities of the method are demonstrated for luminescence in the region of the fundamental absorption
edge of Si and SiGe alloy single crystals. The method is superior in accuracy to previously known luminescence methods of
determining the band gap of indirect-gap semiconductors and practically insensitive to different conditions of outputting
radiation from the sample. 相似文献
