文章中主要阐述了PN码的捕获，并对以前的各种捕获方法进行了改进。得出了基于FFT的快速捕获算法！(Abstract-A FFT-based parallel acquisition algorithm for Direct Sequence/Spread Spectrum radio navigation system is studied to solve long PN code acquisition using serial method. Frequency domain analysis of FFT to acquire signal is applied in this paper and state transfer function is used to derive the expression of average acquisition time.)
