Radar altimeter is a kind of very important microwave sensing instrument for observing the earth, and there are a lot of key technologies involved in the high resolution spaceborne radar altimeter ( hrsbralt ). the principle of hrsbralt, the acquisition and track methods, the if simulation, the closed loop internal calibration method, the pulse repeat frequency ( prf ) design, and the ocean - land compatible altimeter design are studied in this dissertation
雷達高度計是一種重要的微波遙感儀器，本文就高解析度星載雷達高度計的工作機理、跟蹤方法、大時帶積在軌閉環內校準以及海陸兼容等內容進行了深入的研究，具體包括以下八個方面的內容： （ 1 ）深入研究了星載雷達高度計的工作機理，並對典型雷達高度計系統進行了分析。 -
The two major advantages of having observing facilities outside our earth s atmosphere are : first, we can get sharper images of objects without the blurring effects of our atmosphere imagine seeing through a steamy room after you finish taking a bath. second, we can detect radiation from stars and galaxies in frequency bands that have been blocked by the atmosphere, such as ultraviolet, x - ray, and g - ray
在地球大氣外裝設觀測設施有兩大好處，首先，影像可更為清晰，否則大氣的阻隔會使影像變得模糊情形就像身處充滿蒸氣的浴室之中其次，我們可以偵察到那些從恆星和星系而來，卻被大氣層阻擋著的輻射，例如紫外線x射線和伽瑪射線。 -
This is found by observing the doppler shift in the frequency of the radio signals broadcast from the satellite.
這是通過觀測衛星所發射的無線電信號頻率中多普勒偏移來確定的。 -
Apart from a break during the second world war, the frequency of observations, the number of observing stations and the number of meteorological elements observed increased through the years
除了第二次世界大戰期間一度中斷外，觀測次數觀測站數目及氣象要素的觀測項目歷年來都有所增加。 -
This master degree thesis, based on the observing of developing actuality of on - site electrical apparatus monitoring technology, aims at overcoming the problems existing in former on - site monitoring system, such as unable to realize multiple channels sampling and hold, unable to carry out multiple channel programmable magnification, unable to monitor frequency, low pick up bits, external rom low speed data saving, inefficient data query method, inflexible debugging and installation, low precision etc. by introducing eda ( electrical design automation ) technology, we put forward a creative circuit design scheme, which can considerable updated the on - site monitor system
本文根據電氣設備絕緣在線監測技術的發展現狀，針對以往在線監測數據採集系統存在的集成度低，不能實現多通路并行采樣，不能實現多通道同時程式控制放大，不能進行同步頻率監測，采樣位數較低，採用外部存儲器方式，對數據進行查詢的訪問方式，安裝調試不靈活等缺點，提出了應用現代微電子技術電子設計自動化（ eda ）技術實現對在線監測數據採集系統的改進。
