  4. 2. Estimation Problems in Array Signal Processing, System Identification, and Radar Imagery

    Author : Richard Abrahamsson; Peter Stoica; A. Lee Swindlehurst; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parameter Estimation; Array Signal Processing; STAP; SAR; Ground Penetrating Radar; System Identification; Bilinear Models; Covariance Matrix Estimation; Signal processing; Signalbehandling; Signalbehandling; Signal Processing;

    Abstract : This thesis is concerned with parameter estimation, signal processing, and applications. In the first part, imaging using radar is considered. More specifically, two methods are presented for estimation and removal of ground-surface reflections in ground penetrating radar which otherwise hinder reliable detection of shallowly buried landmines.
