摘　　要：研究了前置滤波器对前相关检测方法的影响,并提出一种基于多重前相关差分的GPS信号检测方法。该方法采用前相关差分对多普勒不敏感的优点,提升了前置滤波器在捕获中抑制噪声的能力,通过计算机仿真试验结果验证了理论分析的有效性。The influence of pre-filter on former correlation detection method is studied in this paper, and a GPS signal detection 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 theoretical analysis.
