摘　　要：本文针对线性和非线性调频干扰,通过构建多时频结构特征原子词典,运用匹配追踪算法来实现具有不同时频结构特征调频干扰的分类和识别,依此提出了一个针对调频干扰的识别和分类方法。计算机仿真结果表明,该方法不仅能实现对不同时频结构特征调频干扰的分类和识别,而且不需要预先训练,从而降低算法复杂性,提高了时效性。An approach to the classification and recognition of frequency modulation interference in DSSS based on matching pursuits is proposed through establishing the dictionaries with multiple time-frequency structures. The simulation results show that the frequency modulation interferences with different time-frequency structures are classified and recognized effectively using this approach without need of pre-training. The complexity of algorithm is reduced and the real time performance is enhanced also.
