delay_ekf_non_line

代码说明：

  带时延的纯方位角单站跟踪算法,它有效地解决了用EKF算法进行纯方位角跟踪时可能出现的不稳定和滤波发散现象以及声音信号的时延问题。(Pure time delay with a single station azimuth tracking algorithm, which effectively solved the EKF algorithm with pure azimuth tracking of the instability that may arise and filtering divergence phenomenon, as well as the voice signal delay problem.)
