摘　　要：阐述了混沌码的基本特性,提出用混沌码作为测控扩频码的构想,并讨论了混沌码扩频测控体系构成,以及体系中的关键技术,从而论证混沌码扩频测控体制的可行性,研究表明混沌码比传统扩频码有更强的保密和抗多址干扰特性。This paper presents the basic characteristics of chaotic code, and puts forward proposal of applying the chaotic code for the TT＆C （Telemetry, Tracking and Command） system as a spread-spectrum code. The structure of spread-spectrum TT＆C system and key technologies are discussed to prove the feasibility of spread-spectrum TT＆C system based on chaotic code. The study shows that the chaotic code are more excellent than traditional spread spectrum code in the encryption and anti-MAI （Multiple Access Interference）.
