中频采样的线性调频脉冲信号恢复高频信号的研究

A study on the recovery of HF signals from IF-sampled LFM signals

提出了一种将中频采样信号恢复为高频信号的算法,证明了线性调频脉冲信号的频谱特性与信号中频无关,给出了方法可行的限制条件。

An algorithm recovering HF signals from IF-sampled LFM signals is proposed, proving that the spectrum characteristics of LFM signals is independent of the IF of the signals. The restrictive conditions of the algorithm are also given.
