摘要：

This paper analysis the characters of coherent integration, non-coherent integration and differentially coherent integration based on the structure of partial matched filter (PMF) and Fast Fourier Transform (FFT). It confirms the differentially coherent integration is appropriate for the PMF+FFT. And compared with non-coherent integration, it provides higher performance in the condition of weak GPS signal.
