摘　　要：DS信号是一种具有优良电子防御能力的新型通信信号,广泛运用于军事、民用通信系统中。对抗这种技术的侦察手段目前还没有取得实用性的进展,因此,需开展大量的理论和实践工作。总结了在低信噪比下对直接序列扩频信号侦收的方法,并比较各个方法的优缺点,探讨了其中一些关键问题和新技术途径。DS signal is a kind of new type of communication, which has an advantage of good electronic defensive abilities. This technique has been widely used in many military and civilian aspects. There still remain unsolved problem on the countermeasures for such kind signals. Thus a large amount of theoretical and practical work should be done. The methods used to intercept DS signal in low signal on noise ratio conditions are reviewed, and their advantages and disadvantages are summarized. The important problems are summarized and several promising approaches for solving such problems are proposed.
