解釋
窄頻帶脈沖-
First, this paper research and analyze the feature of signal of pulse doppler radar, and the mathematic model of radar is constructed. the several interference methods that narrow - band suppressing interference, range deception interference and velocity deception interference are discussed. and interference ability is evaluated and simulated
研究和分析脈沖多普勒雷達信號特徵,建立了該種雷達的數學模型,並討論對脈沖多普勒雷達的窄帶噪聲壓制式干擾、距離欺騙干擾、速度欺騙干擾等幾種干擾樣式,並進行干擾性能評估和模擬研究。 -
This dissertation is mainly concerned about the radiation of the tem - horn arrays which radiate uwb ( ultra wideband ) pulse, it mainly involves three parts : theory, numerical stimulation and experiment. the uwb antenna is a new research field in the world which has many differences from nb ( narrow band ) antenna. the most difference is that the uwb antenna such as tem - horn radiates nanosecond pulse which has wide frequency spectrum, but the nb antenna radiates single frequency signal
超寬帶天線是一項新興的研究領域,它與窄帶天線有很多不同之處,最根本的不同在於:超寬帶天線例如tem喇叭天線是輻射納秒級短脈沖信號,這種脈沖信號有很寬的頻譜;而窄帶天線大都是輻射單一頻率時諧信號的。
