Parameter Estimation and Statistical Signal Analysis

Paper abstract
The problem of computing the time-bearing representation for data from a sensor array is considered. A novel approach to dealing with situations where the sources are mobile is presented. The methodology adopted is based on ideas borrowed from the field of time-frequency analysis. Through simulations it is demonstrated that the new approach produces time-bearing plots with greater resolution that conventional methods. Further it is demonstrated that this approach yields bearing estimates with smaller variances than can be achieved using conventional techniques.
