Abstract : This research addresses the problem of efficiently estimating target positions almost continuously in time and establishing correct associations between the estimates of target positions made at different points in time. A complete package was developed for angles-only tracking using sensor array data, which can be implemented in real-time without unduly heavy computations. The method is quite general in nature and can be extended to tracking targets in terms of positional coordinates. The authors also developed a unified theory of robust estimation with minimal assumptions, and investigated problems in probability theory, nonlinear time series, bootstrap methodology, and shape analysis, all of which are useful in signal estimation and imaging. A new line of research was initiated in the use of differential geometric methods in statistical inference.
