Radar emitter identification based on multiresolution analysis

结合信号融合识别的应用需求与多分辨率分析的特点,提出了一种基于多分辨率分析的雷达信号融合识别算法。该算法对获取的信号先进行小波变换后直接对信号进行融合识别。仿真实验表明:该方法在减少数据量的同时能够降低信息的损失,提高信息利用率,较好地保证信息的完整性,可有效提高信号识别性能。

Combining the need of signal-level fusion with the characteristics of multiresolution analysis, this paper has proposed a radar emitter identification algorithm based on the multiresolution analysis. The algorithm can first perform a wavelet transform of the received signal and then make a fusion identification of the signal directly. The simulation results show that the proposed algorithm can reduce the loss of information while decreasing the data capacity and increase the availability of information so as to guarantee the completeness of information and improve the performance of signal identification.
