Calculations indicate that the carrier phase takes effect till the time width of the pulse envelope becomes smaller than the period of the carrier oscillation , and the interpretation of this phenomenon is also presented . it is the difference between phase delay and group delay that causes the sliding between the carrier and the envelope 数值分析的结果表明，当脉宽小于光波周期时，相位的作用开始显现出来，当脉宽比光波周期长时，载波相位的作用可以忽略，并分析了相位起作用的原因，用解析的方法说明正是相延迟和群延迟之间的差别造成了光载波在脉冲包络下的滑动。
In angle measuring , an antenna configuration and interferometer ambiguity - resolving algorithm are proposed , and to eliminate the error caused by carrier phase error , a correction method is introduced , through which all ambiguity - resolving error can be recognized and he corrected even when the error probability is up to 0 . 42 在测角中，提出了一种干涉仪天线阵结构和干涉仪解模糊算法，针对通道载波相位误差可能引起的解模糊错误，又提出了一种纠正方法，仿真显示，在发生解模糊错误的概率高达0 . 42的情况下，该方法仍然可以识别并纠正所有解模糊错误。
In order to attain high accuracy of gps satellite navigation , positioning and low cost in precision agriculture , it is studied a method of gps pseudo - range observation and carrier phase measurement to combine the actual conditions of agriculture . it is presented a method of high accuracy positioning and measure based on gps oem board in this paper , and proved the feasibility of key technology with emulations and field tests 为了适应精准农业高精度、低成本的gps定位导航应用要求，本文通过对gps伪距和载波相位定位方法的研究，结合精准农业的实际情况，提出了基于gpsoem板的高精度定位与测量方法，并用仿真和田间试验验证了各关键技术的可行性。
Furthermore , it is insure that the carrier pahse measurement data does not have cycle slips in gps based attitude determination system , using phase rate prediction algorithm and baseline length constraint information algorithm , the cycle slips can be detected and corrected successfully , which markedly reduce the initialization numbers of attitude determination system 此外，在gps姿态测量系统中，必须保证载波相位观测数据中无载波相位周跳，本文提出的多普勒预测算法和基线长度约束相结合的方法能有效的检测和修正载波相位整周模糊值固定前和固定后的周跳问题，减少了姿态测量系统重新初始化的次数。
