| 摘 要： | 非合作情况下，跳频信号参数准确快速的估计对于获取对方通信参数、产生跟踪式干扰等具有重要意义。提出了一种基于固有时间尺度分解的跳频信号跳速的快速估计算法，该算法迭代地分解跳频信号成一系列固有旋转分量，并求出由各层旋转分量信号包络瞬时幅度的最大值所构成的一个分析序列，对该序列进行傅里叶变换即可估计出跳频信号的跳速。该算法具有运算复杂度低、不受时频不确定性原理影响、时频定位精度高的优点。仿真结果显示，该算法能够有效地估计出跳频信号的跳速。

| Abstract: | In non-cooperative condition,it is of significance to estimate the parameters of frequency hopping signals accurately and rapidly for capturing the communication parameters of hostile part and generating track jamming.An intrinsic time-scale decomposition based algorithm for rapidly estimating a frequency hopping hop rate is proposed.In this algorithm the frequency hopping signal is iteratively decomposed into a series of proper rotation components and a new sequence is derived which is composed by the maxi... |
