该算法对 变换后的时频矩阵，采用求“岛”理论，完成每一跳自项时频点提取

After the algorithm frequency transformation matrix, using the theory of seeking the "islands" to complete the frequency point extracted from the items one at each hop, each time-frequency matrix construction, according to the last-frequency matrix parameters corresponding to each of the original hop, complete when jump, jump cycle, set parameters such as frequency hopping estimate.

The algorithm uses the "island" theory to extract each hop from the item time frequency point, constructs each time frequency matrix, and finally estimates the parameters such as the original time frequency matrix parameters corresponding to each hop, completes the hop time, the jump cycle, the frequency set and so on.

For the transformed time-frequency matrix, the algorithm uses the "island" theory to extract the time-frequency points of each hop's self term, construct each time-frequency matrix, and finally estimate the parameters of the time-frequency matrix corresponding to each hop, such as the time hopping, the period hopping, and the frequency hopping set.<br>
