Three - port error model is analyzed and the procedure for control , calibration , test and display of this system is programmed . three - port device with one port terminated with a 50ohm termination is tested with two - port vna 分析了三端口测量系统的误差模型,编制了误差模型的校准程序和整个系统的测量程序,实现了控制、校准、测量的自动化。
In order to make sure the spacecraft can fly in any condition here adopted the error model was derived by friedland in 1978 , which was based on the earth centered inertial ( eci ) frame 为了能有利于卫星等航天器高精度自主导航本文采用1978年由friedland提出的基于惯性坐标系下的惯性系统误差理论推导出另外一种基于惯性坐标系下的惯性导航系统。
In this simulator , a new error model is introduced , which takes into consideration both the frequency of the errors ( error occurrences following a poisson law ) and their gravity ( burst of errors or single errors ) 为了能够更为确切的模仿电力线的信道。在仿真模型中,引入一个新的错误模型,它不仅考虑到了错误发生的频率,还考虑到了它的强度。
Triggering time synchronization error model is derived , and based on phase noise model of frequency source , random synchronization error is considered . the effect of fixed and linear error on focusing quality is given by simulation 仿真试验给出了固定、线性、正弦及随机型触发时间同步误差对点目标成像指标的影响,同时给出了相应的面目标仿真结果。
Two new error models in terms of quaternion algebra are developed : the additive dual quaternion error model and multiplicative dual quaternion error model . both are expected to facilitate the future dual quaternion - based integrated navigation filter . 4 导出了两个完全用四元数代数表达的误差模型:加性对偶四元数误差模型和乘性对偶四元数误差模型。
