- The second is to assure a multiple - parameter matrix characteristic equation has no nonzero pure imaginary roots . the key of this part is to verify that the structured singular value of a one - unknown matrix function is not equal to one . this work can be accomplished by a frequency sweeping test method
前者的核心是判定某常矩阵的结构奇异值不等于1 ，这只需计算常矩阵的结构奇异值；后者的核心是判定某个以频率为变元的矩阵的结构奇异值不等于1 ，这一问题由频率扫描测试法解决。 - In the leakage characteristic test , the problem of small leakage flow automatic test is solved with the method of usage of an ellipse gear flow meter and a self - made interface circuit . in the dynamic state characteristic test , frequency sweeping and statistic methods are used and their results are compared with 1250 frequency response analyzer
在电液伺服阀动态测试实验中，采用了扫频法和统计法这两种不同的方法进行测试，并对实验结果与1250频响分析仪所测的结果作了对比，发现二者基本一致。 - Frequency sweep flight technique is used to collect the flight data of a model helicopter near its hover and low speed working condition , window frequency spectrum is combined to obtain the frequency response of both lateral and longitudinal channels , then weighted fitting method is utilized to obtain the transfer functions of the two channel
摘要利用扫频试飞技术获取了某无人直升机在悬停工作点附近的舵机输入和直升机动态输出数据，利用组合窗频谱分析的方法获取了直升机横滚通道与俯仰通道动态的频率响应特性，利用加权拟合的方法获取了各自的传递函数。 - In this thesis , based on this kind of application , we made theoretical analysis and engineering practice on high - precision lfmcw and its signal processing millimeter wave broadband lfmcw radar has quite high theoretical range - precision and distance resolution , however , for the real radar system , the nonideal parameter of its transmitting signal , such as power fluctuation and the nonlinearity in frequency sweep , will result in the decreasing of the practical rang - precision and the distance resolution of radar
本文基于这一应用对高精度lfmcw测距雷达及其信号处理进行了理论分析和工程实践。毫米波宽带lfmcw雷达具有很高的理论测距精度和距离分辨力,但对于实际的雷达系统,其发射信号的非理想参数-扫频功率起伏和扫频非线性,将使得雷达的实际测距精度和距离分辨力下降。 - The frequency sweep microwave interferometer of this thesis mention is a good system to diagnosis plasma . the system is simple to operate and the outcome is precise . the fruits of this paper will help the development of microwave interferometer and it ' s social effect is evident
