Abstract
In view of the scholars’ review that satellite is the main cause of correlation between divergences of code-carrier of BD satellites( BDS) and observation angle,a high precision method of measuring mul-tipath caused by satellite is presented. This method gets narrow time pulse by using continous frequency modulated signal,and acquires interested multipath signal by time domain window function,in order to ob-tain the high precision time delay and intensity of multipath signals. By theoretical analysis and test verifi-cation,the method is proved to be simple and effective,and high performances of time domain distinguish-ment and measurement precision are achieved. Based on the method, the conclusion is drawn that mul-tipath of satellite is not the cause of the divergences of code-carrier.关键词
