Abstract: 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.
