电离层巴克码信号处理流程

对接收信号做脉压,本程序使用了三种方式

  • phased.MatchedFilter 函数构造匹配滤波器
  • matlab函数xcorr 直接做互相关
  • 相关的fft实现, 手写实现的matchedFilter函数

解析报文方式修改

增加的函数如下

  • [codew, pulsew, prt, fs] = readTxParameters(echoWaveTables)

    解析完报文之后直接读取码宽、脉宽、PRT和采样率等参数

  • rangegates = readRangeLimits(echoWaveTables)

    利用波门前沿、宽度、采样率等直接计算距离门范围

  • rdata2 = constructRadar2D(echoWaveTables)

    直接构建雷达快慢时间二维矩阵

注意!

巴克码实验的数据找小蔡师兄要。
