As a role instrument , microwave radiometers have been employed in radio astronomy , remote sensing , missile guide and measurement of objective characteristic extensively , with typical mode of all - power radiometer and dicke radiometer 微波輻射計在微波遙感儀器中占有重要的地位,在射電天文、遙感、制導和目標特性測量等方面得到了廣泛的應用。

“ to help them in this seemingly impossible endeavor , the researchers used radio astronomy data , which provided the relative speeds at which the galaxies and their constituent parts are currently moving 為了給他們這種令人難以置信的努力提供幫助,研究人員使用了射電天文學的資料,這種資料為星系以及組成部分當前的運行提供了相關速度。

In hong kong , it is becoming difficult to find a starry night . radio astronomy may be helpful in overcoming this difficulty since radio telescopes are usable at all times and at any weather conditions 在香港,天文愛好者想找一個繁星點點的晚上已經不容易,然而射電天文學可突破這個障礙,因為射電天文望遠鏡可以全天候,不分晝夜運作。

In modern radio astronomy , these radio celestial bodies are called “ discrete sources ? cassiopeia a , cygnus a and taurus a are some examples of discrete sources . the letter “ a “ represents a strong radio source 在現代的射電天文學中,這些射電天體稱作分立射電源,例如仙后座a ,天鵝座a和金牛座a等, a是代表強的射電源。

The first serious attempt to listen for possible radio signals from other civilizations was carried out at the national radio astronomy observatory in greenbank , west virginia , in 1959 and 1960 第一次系列地收聽來自其他文明社會的可能的無線電信號,于1959年和1960年在位于西弗吉尼亞的格林邦克的國家射電天文臺里進行。

He baoyu ( aerocraft design ) directed by wu ji synthetic aperture technology in radio astronomy is introduced into microwave radiometer since 1980 ' s 八十年代以來,為改善微波輻射計性能,人們將射電天文觀測中的孔徑綜合技術引入到微波輻射計設計中,開始了綜合孔徑輻射計的研究。

Mark adams , a spokesman for the national radio astronomy observatory , says that his institute has not yet been told how much money it must raise to keep the vlba open 國家射電天文臺的發言人,表示他的協會還沒有被告知要提高多少錢才能維持vlba運行。

For instance , radio astronomy allows observations of cosmic microwave radiation , thus offering a way of detecting the edge of the universe 例如,電波天文學提供了宇宙微波輻射的觀察,而能夠探測宇宙之邊緣。

The technique has been highly successful in radio astronomy , and in both satellite and aircraft borne radar 該技術在射電天文學、衛星雷達和機載雷達上均獲得了巨大成功。

In none of these respects does optical astronomy have any advantage over radio astronomy . 在所有這些指標上,射電天文并不比光學天文遜色。

Radio astronomy has greatly increased our understanding of the universe . 輻射天文學大大地增進了我們對宇宙的了解。

Radio astronomy today is armed with the largest antennas in the world . 射電天文學擁有世界上最大的天線。
