This paper starts the research of the liquid floated pendulous accelerometer testing system according to the engineering. at first, this paper gives the brief introduction of the history and present status of accelerometer and its testing technology, the working principium and math model of the liquid floated pendu - lous accelerometer, and then, decides the binary width pulse force retrim loop as the design proposal of testing system, researches the transfer function of every part in the system emphasizly, analyses the stability of the whole accelerometer testing system from the angle of control theoretics by the open loop transfer function of system, and designed the correcting net, analyses the basal problems such as resolution, sampling restraint, precision and so on, designs the hardware testing circuits such as preamplification, band - pass filter, alternating amplifier, phase sensitive demodulatorn, pulse - width modulation, frequency scale circuit, moment current generator. finally, using the graphics program language labv - iew which is designed for testing field especially by ni accomplishes the solfware design of testing system, realized the testing functions
首先對加速度計及其測試技術的發展歷史和現狀，液浮擺式加速度計的工作原理和數學模型等作了簡要的介紹，然後確定了以二元調寬脈沖再平衡測試迴路為設計方案，並從控制理論的角度進行了分析，著重研究了系統中各部分的傳遞函數，利用系統開環傳遞函數分析了系統的穩定性，同時設計了系統的校正網路;分析了二元調寬脈沖再平衡測試迴路的解析度、采樣約束以及測試精度等基本問題，並按照系統分析的結果設計了包括前置放大、帶通濾波、交流放大、相敏解調、脈寬調制、頻標電路以及力矩電流發生器等測試系統各部分硬體電路，驗證了電路的正確性，最後按照測試系統的要求，採用了美國ni公司專為測試領域所開發的虛擬儀器工具? ? labview作為測試軟體開發工具，利用該圖形化編程語言完成了測試系統軟體部分的設計，實現了測試功能。 -
As can be seen, the user interaction from these types of filters is mainly limited to two button operation ? correcting wrongly identified messages ? and the more accurate the filter, the less those buttons are used
可以看出，用戶互動過濾這些類型的主要限於兩個按鈕操作糾正錯誤訊息鑒定- -和更準確的過濾，用較少的按鈕 -
The presented dissertation mainly discusses the non - linearity existing in monostation and multistation radar measurement. the first part of this dissertation integrated the non - linearity with the uncertainty of measurement system, and presents a secondary order filter for correcting measuring variance while the measurement equation is non - linear. by comparing the filter error of extended kalman filter with that of secondary order filter, we find the filter performance of these two filters are almost same
本文主要討論單站與多站雷達中的非線性測量問題，在1中，我們把測量系統的非線性與測量系統的不確定性聯系起來，針對只有測量方程是非線性的情況，給出了一種修正測量方差二階濾波器，並用這種二階濾波器分析了推廣kalman濾波器的濾波誤差，指出推廣kalman濾波器與二階濾波器相比，濾波性能幾乎相同。
