    • An electromagnetic transmission system is provided, comprising: M chirp generators, each operating at a first frequency, each of the M chirp generators being configured to generate an ith digital chirp portion comprising (1/M)th of a digital chirp signal having a set ramp rate; a parallel-in serial-out register configured to receive the M digital chip portions in parallel at the first frequency, and configured to output the M digital chip portions in series as the digital chirp signal at a second frequency; and a digital-to-analog converter operating at the second frequency and configured to convert the digital chirp signal into an analog chirp signal, wherein i is an index that goes from 1 to M, and wherein the second frequency is M times the first frequency.
    • 提供了一种电磁传输系统,包括:M个啁啾发生器,每个啁啾发生器以第一频率操作,M个啁啾发生器中的每一个被配置为产生第一数字啁啾部分,其包括具有一组的数字啁啾信号的(1 / M) 坡度 并行串行输出寄存器,被配置为以第一频率并行地接收M个数字芯片部分,并且被配置为以第二频率输出串联的M个数字芯片部分作为数字线性调频脉冲信号; 以及数模转换器,其以第二频率工作并被配置为将数字线性调频信号转换为模拟线性调频信号,其中i是从1到M的指数,并且其中第二频率是第一频率的M倍 。
