解釋
精確速度控制-
After analysing several kinds of light - weighting structures through ansys, hexagonal speculum structure is confirmed. in the aspect of the controling of speculum, the paper adopts the brushless dc motor which is partial assembled to drive the point speculum and the inductosyn as angle measuring component is selected, the ad2s80a the system is used to get directly angle and angular velocity. double closed - loop speed and position control is designed, as the pid control is the well - developed algorithm, which can achieve stable rotation and precise position control
在指向反射鏡的擺動控制方面，採用低速性能好的分裝式直流力矩電機作為指向反射鏡的驅動電機，並採用感應同步器作為角度測量元件，運用軸角轉換器ad2s80a進行角度和速度的輸出，採用技術成熟的pid控制方案，進行速度和位置雙閉環控制，以實現指向反射鏡轉動速度的平穩性和位置的精確性。 -
The procedure can not only resist the influence of outlying kinematic model errors, but also control the effects of measurement outliers. 9. the precise velocity can be determined respectively with precise positioning results, receiver raw doppler measurements and carri
討論了gps姿態測量中模糊度解算、姿態角解算等問題，並基於非專業姿態測量接收機，給出了gps姿態測量的初步結果。 -
In view of characteristics of seismic data of gobi - sand dune areas, this paper, through various data - processing means such as quality control, high - pass filltering, dip angle filltering, field static correction, surface consistency deconvolution, precise velocity analysis, denoising before stack, multiple iterative operation of residual static correction, denoising after stack and modification after shift, has raised the data quality of seismic profiles in low signal - to - noise ratio areas and managed to form the seismic data - processing technique for such complex areas as gobi, foreland and dune
摘要針對戈壁、沙丘地區地震資料的特點，通過對原始資料進行質量控制、高通濾波、傾角濾波、野外靜校正、地表一致性反褶積、精細速度分析、疊前去噪、剩餘靜校正多次迭代、疊後去噪和偏後修飾等處理，提高了低信噪比地區地震剖面的資料質量，摸索出了一套戈壁、山前、沙丘等復雜地區地震資料處理技術。
