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, frequency hopping parameter estimation.

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, and the jump cycle, frequency and other parameters.

For the transformed time-frequency matrix, the algorithm uses the "island" theory to complete the time-frequency point extraction of each hop's self term, and construct each time-frequency matrix. Finally, according to the original time-frequency matrix parameters of each hop, it completes the estimation of the parameters such as the time-frequency hopping, the period hopping and the frequency hopping.<br>
