The analyse of theary about effect on angular error for reflective characterisitic of move angular cone prism 角度誤差影響運(yùn)動(dòng)角錐棱鏡反射特性的理論分析
The compensative relations between the tilt angular errors and groove - width difference were obtained and the compensative methods were discussed 針對(duì)光柵拼接中的轉(zhuǎn)角誤差和光柵常數(shù)誤差,得到了誤差間的相互補(bǔ)償關(guān)系式,并對(duì)補(bǔ)償方式進(jìn)行了討論。
Angular calibration of radar antenna system is composed of the calibration of angular error sensitivities ( also called directional sensitivity ) , adjustment of cross - coupling of azimuth and elevation signals , and the calibrations of system errors such as antenna axial system error , dynamic delay and so on 雷達(dá)系統(tǒng)天線的角度標(biāo)校包括對(duì)系統(tǒng)角誤差靈敏度(又稱定向靈敏度)的標(biāo)定、方位俯仰信號(hào)交叉耦合的調(diào)整以及對(duì)天線軸系誤差、動(dòng)態(tài)滯后等系統(tǒng)誤差的標(biāo)定。
At last , the paper did a detailed analysis on the measurement principle , measurement method , measurement data and measurement precision . explicit the purpose and meaning of measuring the static precision of turn table . after comparison the author decided the reasonable and fitting method to measure the turn table ’ s static precision which include turn table ’ s angular error , intersection and perpendicularity 最后,本文將重點(diǎn)放在了轉(zhuǎn)臺(tái)機(jī)械臺(tái)體的靜態(tài)精度測(cè)試方面,明確對(duì)轉(zhuǎn)臺(tái)機(jī)械臺(tái)體靜態(tài)精度測(cè)試的目的,指出靜態(tài)精度測(cè)試包含的三個(gè)內(nèi)容,即轉(zhuǎn)臺(tái)的回轉(zhuǎn)精度測(cè)試、軸系相交度測(cè)試和軸系垂直度測(cè)試。
