We present an analysis of parameter variance statistics for the TLS-Prony method applied to damped exponential signals. We derive the covariance matrix of the estimated parameters for this method. The parameters include the magnitudes and angles of t

The paper introduces a modified TLS-Prony method that incorporates data decimation. The use of data decimation results in the reduction in the computational complexity because one high-order estimation is replaced by several low-order estimations. Th

A complete Cramer-Rao bound (CRB) derivation is provided for the case in which signals consist of arbitrary exponential terms in noise. Expressions for the CRBs of the parameters of a damped exponential model with one set of poles and multiple sets o

Linear filters can be designed to pass signals of interest and suppress undesired signal components. Wiener [1942] originated work to determine conditions for an optimal linear filter. The present paper reviews the problem of optimally reconstructing

A method for modeling full polarization radar target is considered. The approach taken is to estimate a set of target features which describes the target as a set of attributed scattering centers. Each scattering center is characterized by its range,

The adaptive filter has applications in noise reduction, echo cancellation, and equalization. In this paper, we present an implementation of the sliding frequency-domain LMS (SFDLMS) adaptive filter used as a noise canceller. A compelling interest in

The recently developed 2-D TLS-Prony technique is applied to a single and full-polarization synthetically generated radar data set. The radar target analyzed is a generic aircraft consisting of a fuselage, wing, stabilizer, and tail. The 2-D TLS-Pron

Scattering centers extracted from radar returns are features that can be used for automatic target recognition (ATR). Most scattering center extraction algorithms fall into one of two large classes: FFT-based and model-based techniques. In this paper

A new two-dimensional (2-D) technique is developed to estimate the polarimetric characteristics of scattering centers that exist on radar targets. This technique uses a 2-D damped exponential model to approximate the scattering from radar targets. Th
