高重頻多注速調(diào)管發(fā)射機(jī)110 - Range of pulse repetition frequency
脈沖重復(fù)頻率范圍 - Pulse repetition frequency
脈沖重復(fù)頻率 - This paper ' s study is focused on the principle of bistatic sar on the basis of giving a brief introduction of sar principle , including azimuth resolution , mapping width , focusing deepness , pulse repetition frequency limitation and radar equation etc . then the paper studies the special form of bistatic sar with stationary transmitter
在簡要介紹了合成孔徑雷達(dá)的成像原理后，本文著重從原理方面對雙站sar進(jìn)行了分析，討論雙站sar的方位向分辨率，測繪帶寬，聚焦深度，脈沖重復(fù)頻率限制，雷達(dá)方程等問題，然后對發(fā)射機(jī)固定的雙站sar這種特殊的雙站sar模式進(jìn)行分析。 - Synthesized signals with different pulse repetition frequencies ( prf ) and main vibration frequencies ( mvf ) were presented to the brown planthopper . the results showed that prf was a sensitive and important signal characteristic in mating choice . the prf and mvf sensitive ranges of male signals were 70 ~ 90hz , 200 ~ 1700hz separately , and of female signals were about 22hz , 100 ~ 300hz separately
雄蟲敏感的prf范圍在22hz左右，雌蟲敏感的paf范圍為70 90hz ，這與實(shí)際的雌、雄蟲求偶鳴聲的pm變化范圍是一致的；雌、雄蟲能對mvf變化范圍較大的信號敏感，雄蟲敏感的mvf范圍為100 300hz ，與雌蟲求偶嗚聲的mvf變化范圍是一致的，而雌蟲敏感的mvf范圍為200 1700hz ，要比實(shí)際的雄蟲求偶鳴聲的mvf變化范圍大的多。
