基于信号的核函数的时频表示可以有效地抑制或转移交叉分量，提高时频表示的可读估计，改善其主要性能。

The TFRs with signal-dependent kernel can suppress and translate the cross-components, improve the readability and main performances.

针对跳频信号的非平稳性，提出了基于时频表示的跳频信号分析方法。

A new analysis of frequency hopped sequence based on time frequency presentation is proposed in the paper.
