雷达敌我识别干扰方法研究 总被引:1,自引:0,他引:1
雷达敌我识别系统用来识别雷达发现目标的敌我属性,它的基本原理是询问机发射射频脉冲询问信号给应答机,应答机收到后自动发回应答信号完成敌我识别;雷达敌我识别干扰则是利用己方的雷达敌我识别对抗装备对敌方的雷达敌我识别系统实施电子干扰的作战行动。文章通过阐述基本工作原理、分析典型信号特征,介绍了雷达敌我识别系统;针对其存在的弱点,分析了雷达敌我识别干扰的可行性;结合已有研究成果和可行性分析,探讨了压制性干扰、欺骗性干扰和灵巧干扰的方法,对雷达敌我识别对抗技术的深入研究具有一定的意义。 相似文献

The temperature dependence of refractive index of polymer films was determined for a number of slab waveguides by a grating coupling method. This dependence was examined as a function of parameters such as molecular weight and glass transition temperature of the polymer. Temperature-induced changes in N TE-N TM , N being the effective index, were studied systematically for different slab waveguide compositions. It is shown that with proper device design and choice of polymeric materials, thermal effects can be reduced 相似文献

The approaches to prepare a uniform and unified scientific terminology of chemical carcinogenesis are presented. The main definitions proposed (carcinogen, initiation, promotion, mutagen, multistage carcinogenesis, anti-carcinogen, cocarcinogen, carcinogenic risk, etc.) are based on the current state of comprehending mechanisms of the action of chemical carcinogens. 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
