摘要:

针对噪声环境下的跳频信号，提出了一种基于稀疏分解的时延估计方法。对跳频信号采用稀疏分解重构进行了研究，在此基础上，在不同天线下对跳频信号分别进行重构，得到每跳信号对应的载波频率和时间中心，从而估计出跳频信号的时延。仿真结果表明，在信噪比大于7 dB时，跳频信号的时延估计误差基本趋近于零，验证了时延估计方法的有效性。

Abstract:

For frequencyhopping (FH) signal, a novel method of time delay estimation (TDE) is presented in the noise environment. The FH signals are reconstructed by usin g the method of sparse decomposition, then, the TDE of the same hop is estimated through the carrier wave and time center of each hop which are obtained when th e FH signals are reconstructed in the different antenna respectively. Simulation results demonstrate that the error estimation is near zero when the S NR is greater than 7 dB,so the TDE method is effective.
