摘要
本文在分析Wigner Ville分布及其在瞬时频率提取中的应用的基础上,结合脉冲压缩雷达信号的特点,提出了基于中频数字化接收机,采用Wigner Ville分布检测脉冲压缩雷达信号的思路。最后分别针对模拟信号与实际信号进行了计算机仿真实验。
This paper analyzes Wigenr-Ville distribute and its application in extracting of signal's instantaneous frequency. Then it combines PC radar signal's characteristics, puts forward a method for detecting PC radar signal. This method bases on intermediate frequency digital receiver, and adopts Wigenr-Ville distribute. Lastly, computer simulations are carried aiming at simulate radar signals and practical radar signals.
