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, and finally the frequency matrix parameters according to the original time corresponding to each 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 timing matrix corresponding to each hop, and the jump cycle, frequency and other parameters are estimated according to the parameters of each hop corresponding to the time frequency matrix.

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