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

    Författare :Richard Abrahamsson; Peter Stoica; A. Lee Swindlehurst; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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; Signal Processing; Signalbehandling;

    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.

  3. 3. Efficient Parallel Architectures for Future Radar Signal Processing

    Författare :Anders Åhlander; Chalmers University of Technology; []
    Nyckelord :radar signal processing; space-time adaptive processing; Keywords: computer architecture;

    Sammanfattning : The processing demands on future embedded radar signal processors may stretch to severaltrillions of floating-point operations per second (TFLOPS). This is an increase of two to threeorders of magnitude relative to the requirements of today. Still, the tight size and powerconstraints are unchanged. LÄS MER
