高噪声背景下的罗兰-C信号相位编码识别研究
Research on Phase Coding Identification of Loran-C Signal in Strong Noise Environment
摘要
Abstract
The loran-C receiver may fail to identify phase code of the Loran-C pulse in strong noise environment. The identification prin- ciple of the Loran-C carrier signal initial phase based on all-phase Fast Fourier Transform （apFFT） spectrum analysis is analyzed on details. After studing on the method for Phase coding identification of Loran-C signal with strong noise based on apFFT, Monte Carlo simulation of the new phase measuring method is completed with MATLAB, quantitative analysis showing that the method based on apFFT can estimate the initial phase of carrier wave in strong noise environment without any steps for eliminating noise, identify Lhe phase code of the Loran C pulse properly, and it can be introduced to the modern eloran receivers.关键词
