一种基于FFT块处理的微弱GPS信号检测新方法
A new acquisition method of weak GPS signal based on FFT block process
摘要
Abstract
In this paper, a new acquisition method of weak GPS signal based on FFT block process is studied. Compared with traditional alternate half-bit coherent integration method, new method is more effective and time-saving,while less amount of GPS data is needed. Simulation experiment result shows that,through at most 300 ms GPS data,new acquisition method can acquire weak GPS signal at the 24 dB-Hz level of CNO power.关键词
