摘　　要：针对短波跳频信号跳速慢、一跳持续长、多径效应的特点,采用多窗口叠加,把截获信号分成若干段,分别对其进行重排Gabor谱分析,提取频率脊线,再把脊线按顺序拼成一个整体,从而提取跳频信号的参数。For the HFFH signal has some characteristics such as slow-hop, single hop with longer time, multi-path, it is separated into many segments and analyzed using Gabor spectra reassignment . Then the relationships of the time and frequency are picked up. After that, relationship of the time and frequency of each segment is put together to estimate the parameter of the signal.

关 键 词：短波跳频 参数估计 Gabor谱 重排
