scattering body meaning in Chinese

散射体

First in this paper , we review the development of radar signal processing and cfar detector , analyse the structure and principle of the signal processor , ca - cfar and os - cfar detectors . then , in view of the characteristic of prc cw signal , analyses the statistics characteristic of scattering bodies , models of target , noise , ground - clutter and weather - clutter are made . these lay a theoretic foundation of signal processing and cfar detector
然后,本文针对x波段伪随机m序列相位编码连续波信号体制,分析了各种散射体的统计特性,对雷达目标及检测背景噪声(热噪声、地杂波和气象杂波)进行了理论分析和统计检验,建立了目标及检测背景的目标模型,确立了信号处理和恒虚警检测的理论基础。
A new study of specially spherical - glowing optical fiber is present in this paper , a large core silica optical fiber is melt the ball and is spread all scattering body evenly on the round spherical terminal surface , which is melt the ball to the spherical terminal surface again , thus getting the output optical fiber needed . 4 . designing the system of testing the specially spherical - glowing optical fiber
3 .设计研制了一种特殊球形输出光纤,实验中采用大芯径石英光纤,利用光纤熔接机对石英光纤端面进行熔球,在圆球形端面上均匀涂上光散射体,对所得的球形端面再次进行熔球,从而得到所需要的输出光纤。
