Abstract

Techniques concerned with the problem of complex spectral estimation are of great importance to many modern applications, one of which is the inverse synthetic aperture radar (ISAR) imaging, In this paper we study a variation of the non-parametric Amplitude and Phase Estimation of a sinusoid (APES) method that is produced by a parameterization of its noise covariance matrix Q. Computer code using the MATLAB software was produced for the study of the modified estimator and numerical examples using 1-D synthetic data are presented to demonstrate several of its properties.
