系統採用電臺的電視伴音調頻信號,其中電臺信號與伴音信號功率之比基本為10 : 1 ,並且目標散射信號較弱,一般情況下淹沒在雜波和機器熱噪聲之下,採用常規的脈沖檢測方法很難對遠距離的目標進行檢測,而以電臺直達信號作為參考與目標回波信號進行相關檢測;系統中信號的相關處理會產生旁瓣,而強目標的旁瓣會影響附近的弱目標檢測。Orotund frequency of of tone of high and low, main with the each vibration of number of times relevant, is a person s ear to high and low and subjective evaluation dimensions of tone. the tone is low to mean to vibrate the frequency low, the voice seem to be deep and low ; the tone is high, and mean to vibrate the frequency high, voice the stab
音調聲音頻率的高低,主要與音源每秒振動的次數有關,是人耳對音調高低的主觀評價尺度。音調低表示振動頻率低,聲音顯得低沉音調高,表示振動頻率高,聲音就尖刺。The calls of non - passerine are some kinds of monotonous dull vocalizations with the characteristics of low and deep frequency, single syllable, low basic frequency and with no ability of modulation in frequency and amplitude. most of the calls are monotonous and low quality mainly based on the basic song. compare the vocal of sub - oscine passerine with non - passerine, they have some similar aspects, but the former possesses of stronger capability of vocal control
非鳴禽的叫聲低沉而單調,音節種類單一,基本音頻率低,缺乏頻率調制以及幅度調制的能力,叫聲的品質因數很低,不悅耳,大多為以基本音為主的單音調低音品叫聲,亞鳴禽的叫聲與非鳴禽近似,但在控聲能力方面又有所提高。The modulation of sound properties over a wide range of time scales is one of the most obvious characters of oscine passerine ' s vocal, whose song contains many different kinds of syllables that consist of many more multiple song phrases. in oscine passerine, ipsilateral projections of ra to nxiits innervates the ipsilateral syringeal muscles exactly, and thus they have strong ability of vocal control with variable tones, high frequency and higher lever of quality. as a result, the songs sound well
鳴禽鳴囀的最大特點之一便是其單次鳴唱時間長,鳴唱所包含的音節數量和音節種類繁多,因而由這些音節所組成的句型結構也是復雜多樣富於變化,且由於nxiits嚴格的側別控制(每一側核團只支配同側鳴肌) ,使其具有更強的控聲能力,其鳴聲音調變化幅度大,頻率高,品質因數大,音色好,因而其鳴聲也悅耳動聽。Compared with non - passerine, they appeared longer syllable length, higher basic frequency and more viable frequency ranges. though the amplitude modulation properties enhanced their vocal production, the type of syllable is still stable and less of variety. so the phrase consisted of syllables are comparatively few and changes of the tone are relatively less
且表現出很強的頻率調制特性和特有的幅度調制特性,相對的音節時程比較長,基頻較高且頻率變化范圍較大,所特有的幅度調制特性更增加了其控聲的能力,但其音節的種類仍很單一,缺乏變化,由音節所組成的句型較少,音調變化幅度不大,因此,其叫聲質量盡管較非鳴禽有所改善,但相對鳴禽而言卻又遠遠不如。He has also shown how electronic technology can be harnessed to map out and account for phonological developments in china through the example of retroflex initials. mitsuaki endo follows the admirable tradition of toiling with patience and perseverence to provide a foundation that will facilitate research by others. he has compiled frequency data on initials, medials ( glides ), nucleus vowels, rhyme endings and tones in the chinese rhyme book
