基于调幅广播信号的动目标时差提取方法

AM SIGNALS-BASED TIME-DIFFERENCE EXTRACTION OF MOVING TARGETS

分析了调幅信号的循环平稳性,并结合CCC方法得到了基于调幅信号的固定目标时差提取方法;进一步在分析CCC方法不足的基础上得到了运动目标时差提取方法——AM-ECCC方法,仿真结果表明该方法不仅比相关方法性能有明显的提高,并且具有很好的抗噪性能。

Cyclostationarity of AM signals is analyzed and time-difference extraction method based on Cycle Cross-Correlation(CCC) is presented in this paper. An Extended CCC method AM-ECCC method for moving targets is given also. Simulation results show that the given method can work more efficiently in highly corruptive environment than correlation method.
