According to the original Project Proposla, the tow primary directions considered in this research effort are; (1) Advanced signal processing algorithms for digital microwave receivers with Electronic Warfare applications: Significant contribution has been made on estimating the Angles-Of-Arrival (AOA) or frequencies. Specifically, a computationally efficient and accurate Minimum-Norm Method has been developed that does not require any Eigenanalysis. Theoretical Perturbation Analysis of this method has been completed. A Maximum-Likelihood Estimator (MLE) that ensures unit circle frequencies has been developed. Furthermore, a new pipelined adaptive algorithm for Tracking moving targets has been presented. (2) Optimal identification of rational transfer functions: unlike existing algorithms which either modify or linearize the error criterion, the true criteria have been decoupled into (1) a purely linear problem for numerator and (2) a nonlinear problem with reduced dimensionality for the denominator. the decoupled estimators possess global optimality properties buth have reduced computational complexity than existing methods. The results on 1-D cases have been extended for idtntifying Multi-Dimensional systems. In addition, a new 'Distributed Look-Ahead' architecture and an Optimal Approximation Approach have been proposed for high-speed implementation of Recursive Ditigal Filters.

The research in the Year-1 of this project has focused on two primary directions, as originally, proposed, (i) Advanced signal processing algorithms for digital microwave receivers with Electronic Warfare applications: For estimating the Angles-Of-Arrival or Radio Frequencies, a significant contribution has been made with a computationally efficient Minimum-Norm Method that does not require any Eigenanalysis but produces equally good estimates. A Maximum-Likelihood Estimator (MLE) that ensures unit circle frequencies has been proposed for obtaining the most accurate estimates. Furthermore, two new algorithms for improved AR/ARMA spectrum estimator from noisy observations have been considered. Several time-domain and frequency-domain algorithms for detecting the presence of targets are also being studied. (ii) A general and unified theoretical framework for optimal identification of rational transfer function coefficients from: (1) Input-Output data, (2) Impulse Response data and (3) Frequency Response data. Unlike existing algorithms which either modify or linearize the error criterion to estimate the unknown parameters simultaneously, the true error criteria have been decoupled into (i) a purely linear problem for estimating the optimal numerator and (ii) a nonlinear problem with reduced dimensionality for the optimal denominator. The decoupled estimators possess global optimality properties but have reduced computational complexity than existing methods.
