论文提出将频域分段相干累加法应用于P码直捕系统。首先对算法进行了介绍,然后给出了应用此算法的P码直捕的实现方案,分析了在高动态环境下其对硬件资源及工作速度的要求,研究表明应用频域分段相干累加法的P码直捕系统能够适应高动态环境,且大大节省了硬件资源。 The thesis proposes to apply frequency-domain piecewise coherent accumulation method to P code direct acquisition system. Firstly, the algorithm is introduced, and then the implementation scheme of P-code direct capture using this algorithm is given. The requirement of hardware resources and working speed in high dynamic environment is analyzed. The results show that the application of frequency domain segmentation coherent accumulation P-code direct capture system to adapt to high dynamic environment, and significant savings in hardware resources.
