摘要
在航天测控信号高动态环境下,用Logistic混沌码代替直扩捕获系统中的传统伪码,仿真分析了映射参数对捕获系统性能的影响;与m码相关性能作对比并指出了在不同码长、码速率条件下,码型对平均捕获时间的影响。
In the high dynamic environment of TTC signals,taking the Logistic chaotic code instead of tradition code in the direct sequence spread spectrum acquisition system,the effect that mapping parameters to the acquisition system performance is simulated and analyzed.Comparing to the m code,the effect that code style to the average acquisition time is pointed in the different code length and code rate.
