摘要
以周期谱相关理论为基础,讨论了谱相关到达时差估计模型和实现方法,将该模型应用于有噪声和干扰条件下的扩频通信信号的到达时差(TDOA)估计.给出了几种典型情况下的计算机仿真结果,阐明了它对扩频信号的测向和定位具有广阔的应用前景.
Based on the spectral correlation theory, a model and algorithms of time difference of arrival (TDOA) estimation for cyclostationary signals are presented first, and then this model is used for the TDOA estimation of the spread spectrum communication signals in the highly noisy and jamming environment. Some typical results of simulation using a computer are given finally. It is shown that this method can find wide use in the location and direction finding of the spread spectrum communication signals.
