We propose a new directions of arrival (DOA) algorithm which provides very reliable estimates in fast time-varying environments. Popular DOA methods such as MUSIC and ESPRIT cannot be used in these environments because of their reliance on the estimation of a covariance matrix. The algorithm uses a two stage approach. The first stage uses a matching pursuit based algorithm to process each snapshot...
Contour modeling by a time-varying autoregressive (TVAR) model is considered. A least squares estimator of the TVAR model parameters is presented, and the maximum likelihood approach for determining the model order is also presented. In the experiment, curvature extrema points of synthesized contours are detected from the time frequency distribution estimated with TVAR model. In the classification...
