| 摘 要： | 提出了一种新的声表面波（ＳＡＷ）滤波器设计方法。先对设计目标函数采样减少变量数，用Ｚ变换零点分开并通过内插重构得到两组加权初值。假定其中一个固定而对另一加权系数利用标准的雷米兹交换算法进行优化。对Ｂｌａｃｋｍａｎ谱成形成滤波器的模拟设计表明，该方法计算精确方便，简明实用。

| Abstract: | This paper discusses a method of determining GPS carrier phase ambiguity in kinematic environments.Mathmactical model is set up.After searching space is defined,all ambiguity combinations are tested with statistic check epoch by epoch until the only correct one is found.Simultaneously accumulated sum of squares of residuals of every ambiguity combination is calculated which can be used to distinguish the correct ambiguity set from the wrong sets easily.Finally simulations are performed which show this algorithm is effective. |
