模糊度函数 meaning in English
ambiguity function
Examples
- And the resemblance is pointed out between continuous wavelet transform ( cwt ) and waf . in the course of computing waf , the scaling replica is very important . based on the properties of cwt , three approaches have been proposed for the scaling of a wavelet that has no analytic form
详细阐述了宽带信号及系统的三个条件、宽带系统的回波模型和宽带模糊度函数的概念，指出了连续小波变换( cwt )与宽带模糊度函数的惊人相似之处。 - 7 . based on the comparison with dual band gps phase and c / acode , ambiguity function method , least squares search , ambiguity solution covariance , cholesky disintegrate and least square ambiguity decorrelation adjustment , it is considered the method of ambiguity function using double gps antennas to move baseline and the equation of dual differential carrier phase
在分析双频p码伪距法、模糊度函数法、最小二乘搜索法、模糊度协方差法、 cholesky分解法、和lambda算法的基础上，重点研究基于双gps天线动一动基线载波相位双差整周模糊度确定方法。 - After analyzing the existing ambiguity resolution methods the dissertation investigates the baseline rotation method based on the antenna - swap idea , and develops the fixed axis rotation maximum - minimum method ? farmm and the equivalent rotation maximum - minimum method ? ermm applicable for static basement and moving vehicle respectively . the former lowers the demands on rotation device while the latter improves the flexibility of antennae installation . meanwhile the dissertation also brings forward an ambiguity function search method which needs only one single epoch data with the outer aided information , and investigates the accuracy requirements for the assistant pointing information
其次,通过与gps等多星系统定向关键技术的对比分析,指出双星定向模糊度确定的难度;在分析现有模糊度求解方法的基础之上,研究了基于交换天线思想的转动基线模糊度确定方法,并提出了适合于静基座的定轴转动极大/极小值farmm法,以及适合于地面运动载体的等效转动极大/极小值ermm法,前者降低了对转动机构的要求,后者则提高了天线安装的灵活性;同时,提出了一种借助外部辅助信息的模糊度函数搜索法实现单历元双星定向,并分析了对外部辅助单轴姿态信息的精度要求。
