A parameter estimator based on adaptive noise canceller

The application of an adaptive noise canceller to parameter estimating is restricted for its unsatisfactory performance in the condition of high SNR input.Based on an adaptive noise canceller,the article presents a parameter estimating method,which shows nice filtering function and good tracing ability with unknown prior information of interference and motion model of the object.The presented estimator only needs a condition that the interference noise varies faster than the parameter to be estimated.
The presented method as a bearing estimator is used to process the data collected in a sea experiment and the results have shown exciting property.
