摘要
信号的分选和识别是信号处理系统的重要部分,在信号处理中占有举足轻重的作用.目前,空间中的信号环境越来越复杂,对信号的分选和识别而言,难度越来越大.通过对线性调频信号与相位编码信号的分析,讨论了一种基于瞬时自相关的瞬时频率提取的方法,并在后面用匹配滤波器进行信号的匹配.这种方法是对信号分选方法的一种新的尝试.
The signal sorting and recognition technology plays an important role in recent signal processing systems. At the present time, because the signal environment is more and more complex, it is more and more difficult to sort signal in the complex environment. Through the analyses to the linearity frequency modulation signal and the phase coding signal, we discusse a method of instantaneous frequency distilling on the base of instantaneous self correlation, and then, it matches the signal using a matching filt...
