    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; landmines; detection; feature extraction; impulse radar; ground penetrating radar; classification;

    Sammanfattning : The present thesis deals with the problem of detecting and classifying buried objects. The application in mind when addressing this problem is the detection of buried landmines. According to the International Committee of the Red Cross, about 100 million landmines are buried in 62 countries around the world. LÄS MER

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

    Författare :Richard Abrahamsson; Peter Stoica; A. Lee Swindlehurst; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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.
