摘　　要：短波通信干扰包括短波通信瞬态干扰和短波通信长干扰两种。在对短波通信干扰的成因进行分析的基础上,利用特征子空间理论,提出了有效抑制短波通信干扰的方法。这种方法不仅能够消除短波通信瞬态干扰,而且对多个瞬态干扰同时存在所形成的长干扰的抑制也非常有效,这是一般抑制瞬态干扰的方法所达不到的。实测数据仿真结果表明了这种算法的有效性和实用性。Shortband communication interference includes transient interference and long interference.An approach by which shortband communication interference can been eliminated is presented based on the theory of characteristic subspace after analyzing the cause of Shortband communication interference formation.Compared with some methods by which only transient interference can been restrained,this method not only can eliminate transient interference,but also can effectively restrain long interference caused by lots of Shortband communication transient interference.Simulation results in real data show that the proposed method is efficient and practical.
