The acceleration method for convergence rate in digital adaptive sidelobe canceller at radar

摘要

1. the art that the invention defined in the claims; The present invention will on a computer-readable recording medium recording a program for realizing the convergence rate acceleration method and the method in a digital system, adapted to remove side lobe of the radar.; 2. The invention attempts to solve the technical challenges; The present invention, statistical properties of the signals obtained in the previous section in order to obtain a more rapid interference cancellation performance in a limited range of the radar environment as compared to the statistical characteristics of the current interval to obtain the rate for using a statistic of the previous section, it depending intended to provide a computer readable recording medium recording a program for realizing a current in addition to the statistic of the interval to speed up the convergence rate to obtain the weighted method and the method statistics of the previous section.; 3. Resolution of the subject matter of the invention,; The present invention, de-child (DMI) a first stage using an algorithm to obtain the rate for using a statistic of the previous section by comparing the statistical properties of the statistical nature of the current period obtained in the previous section; And including a second stage to obtain a weight by adding the statistic in the previous section according to the obtained ratio to the statistics of the current interval.; 4. An important use of the invention,; The invention yiyongdoem like radar system.
