| Abstract: | The influence of pre-filter on former correlation detection method is studied in this paper, and a GPS signaldetection method based on multiple former correlation differentials is presented.The former correlation differential is not sensitive to Doppler and the ability to restrain noise in capturing is improved, and the simulation results verify the effectiveness of theoreticalanalysis. |
