摘要
伪随机码在测控系统中具有测距码和扩频码的双重功能。相对于常规伪随机序列,混沌序列具有一系列独有特性和优势。把混沌序列应用于测控系统中,将进一步提高系统保密性能,并改进系统功能的实现方法。分析了混沌序列的特点和优势,讨论了其在测控系统中的应用方法及关键技术,提出了测控系统中混沌序列同步的长短码转换法。该方法能够有效解决序列同步问题,并充分利用混沌序列的非周期性,解决距离测量中的模糊问题。
Pseudo noise sequences act as ranging codes and spread spectrum codes in TT＆C Sys tern. Chaotic sequences have a series of particular characteristics and advantages compared with traditional PN codes. The application of chaotic sequence in TT＆C system will improve systematic securi ty and the implementation of ranging method. The characteristics and advantages of chaotic sequence are analyzed. Then the method of how to use chaotic sequences in TT＆C system, together with the key technologies are discussed. A new method to synchronize chaotic sequences is presented. Utilizing the aperiodicity of chaotic sequences, this method can resolve the range ambiguity in TT＆C.
