TV target tracing system has following features: real-time, image indistinctness on the ground of dynamic tracing and external environmental distortion, high noise background intensity and so on.
电视目标跟踪系统实时性强，由于是动态跟踪和外界环境干扰，所以导致图像不清晰、背景噪声较强。
By monitoring of intensity of EM radiation for TV Broadcasting in Jinan city this paper proposed a evaluation conclusion and a distributive law of space and time.
通过对济南市电视广播电磁辐射强度进行监测，提出相应的评价结果和空间与时间分布规律，为济南市城市规划和电视广播电磁辐射监管提供技术支。
LCD TV panels of light transmittance is very low, to produce TV backlight brightness the display needed will need to provide adequate light intensity, and backlight system needs to consume more power.
液晶面板的光透射率极低，要产生电视需要的显示亮度就需要背光提供足够的光强，背光系统需要消耗较多的电能。
Research results show that the relative aperture of optical lens, the incline and defocusing of reflection plane in TV seeker optical system reduce the intensity of the "cat's eye" reflection.
研究结果表明：回波强度受导引头光路中光学镜头的相对孔径、摄像管靶面倾斜和离焦的影响较大；扫描激光光束的入射角等因素对回波强度也有一定的影响。
