This paper describes a new method to select these parameters, including to determine the focus length, relative aperture and field of view of new optical system in design by means of making reference to previous star sensors and their optical systems ; to forecast the acquiring probobility of star sensor in accordance with selected param eters ; to determine the principal design wavelength and spectral coverage by means of integrat ing the spectrum of stars
本文介紹一種確定光學系統參數的新方法，包括通過參考比較已有星敏感器及其光學系統特性來選取新光學系統焦距、相對孔徑和視場；根據所選取的參數預計星敏感器的捕獲概率；採用綜合恆星光譜方法確定光學系統中心波長和光譜范圍。 -
Through some research in depth on soct, this thesis proposes a scheme of star - type vsat ( very small aperture terminal ) network based on overlap back transmission, and do some research on key techniques involved with the scheme and their partial realization with fpga ( field programmable gate array ), such as spread spectrum techniques, a non - coherent de - spreading spectrum and demodulation technique and adaptive interference cancel
本文在深入研究衛星重疊通信技術的基礎上，提出了一種基於重疊回傳的星形vsat網方案。並在衛星重疊通信涉及的幾種關鍵技術及其部分核心器件的fpga實現等方面進行了一些研究，包括：擴頻技術、非相干解擴解調技術、自適應干擾抵消技術等，並將它們用於基於重疊回傳的星形vsat網方案。 -
Usually, the spectrum does not tell us the total energy the star radiates out
通常來說，我們不能用光譜計算出一顆恆星的總能量輸出。 -
If the star emitting the light is moving away from us, its light rays have a longer wavelength ( lower frequency ) by virtue of doppler principle and this is manifested in a general shift of the spectrum lines towards the red end of the spectrum
如果發某種光的恆星離開我們，根據多普勒原理，其光線的波長較長（即頻率較低） ，在光譜上則顯示出譜線全部移向紅端。 -
It is because when atoms are in low pressure, they can only emit or absorb light of certain wavelengths. if some em wave with continuum spectrum passes through some low pressure atoms e. g. the outer atmosphere of a star, those atoms will absorb the light it likes and creates an absorption line
這是由於低壓原子會吸收或發射特定頻率的光線，假若有譜線為連續的光通過這些原子例如恆星的表面大氣，這些原子便會吸收了特定頻率的光線，形成在光譜中有吸收線的現象。 -
Similarly, in the spectrum of a star moving towards us, the characteristics lines would show a “ blue shift ”, i. e., they would be displaced towards the blue end of the spectrum, corresponding to shorter wavelengths and higher frequencies
同樣，在向我們靠近的恆星的光譜上，特徵譜線會顯示「藍移」 ，即譜線移向藍端，就是說波長短而頻率高。 -
For a warm and dense non - gaseous substance in high pressure object such as a star or a piece of metal, it will radiate light electromagnetic wave and the spectrum follows what we call a
除了低壓下的氣體，只要密度較大而不是絕對零度的物體例如恆星或一塊鐵皆會不斷輻射出電磁波，而它的光譜會和一種稱為 -
In general, if the peak of a spectrum is at the red light region, the star will appear to be red
此外，光譜的峰值位置顯示了恆星看起來的顏色，例如峰值在紅光位置，那麼那顆星看來便是紅色的。 -
If you spread the light of a star out into a rainbow and photograph it, you have a spectrum of the star.
如果你把恆星的光分解為彩虹的顏色並且對它拍照，你就得到了恆星光譜。 -
By carefully analyzing the spectrum of a star, we can tell which elements the star s surface may contain
只要小心分析恆星光譜中的吸收線，便可以找出恆星表面的物質成分。
