  1. 16. Sensor Array Optimization for Multiple Harmonic Sound Source Separation and DOA

    University essay from Lunds universitet/Teknisk akustik

    Author : Elisabet Suárez Lopéz; [2013]
    Keywords : Technology and Engineering;

    Abstract : INTRODUCTION In the last years a lot of researches about source separation have been realized, like extraction of a signal of interest (vocal recognition application), identification of which source gives which sound (motor engine applications) or noise source characterization (environmental application). Most of these techniques for sound source estimation use the signal-subspace approach, where the number of emitting sources is determined by the multiplicity of the lowest eigenvalue of the correlation matrix.

  3. 17. Evaluation of weighting functions for Sidelobe control in UWB SAR image processing

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Habiba Akhter; [2013]
    Keywords : Image processing; Synthetic aperture radar SAR ; Ultra Wideband UWB ; Apodization; Impulse Response IPR Function;

    Abstract : Ultra wideband (UWB) Synthetic Aperture Radar (SAR) holds huge possibilities for both terrestrial and celestial object sensing with excellent details which assists in science and technology. SAR systems associated with large antenna beamwidth, large signal bandwidth and low frequency operating in the VHF/UHF region is becoming gradually more popular because of their rising number of application in the areas of ground-penetrating radar (GPR) and foliage penetration radar (FOPEN).

  4. 18. An Investigation of the Polarization States of Light Reflected from Scarab Beetles of the Chrysina Genus

    University essay from Tillämpad optik

    Author : Lia Fernandez del Rio; [2011]
    Keywords : Near-circular polarization; Large ellipticity; Mueller matrix; Spectroscopic ellipsometry; Scarab beetle; Chrysina genus;

    Abstract : The polarization behaviour for six species of Scarab beetles from the Chrysina genus is investigated with Mueller Matrix Spectroscopic Ellipsometer (MMSE). The m41 element of the matrix, which is related to the circular polarization behaviour, is analysed. READ MORE

  5. 19. The Effect of GPS Signal Quality on the Ambiguity Resolution Using the KTH method

    University essay from KTH/Geodesi och satellitpositionering

    Author : Elbashir Mohamed Elbashir Elhassan; [2010]
    Keywords : ;

    Abstract : Since the last decade the integer phase ambiguity resolution has become one of the most important elements in the GPS field because of its impact on the accuracy. Several scientific researches have been carried out for resolving the integer ambiguity. READ MORE

  6. 20. Synthetic Aperture Radar Image Quality Measurements

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Subrata Kumar Das; [2010]
    Keywords : Key Words: SAR; UWB SAR; spatial resolution; differential resolution; ISLR; PSLR; sinc function; IRF-SAR.;

    Abstract : Abstract Synthetic Aperture Radar (SAR) is an important tool for remote sensing now a day. SAR image quality measurements play an important role in the development of SAR image digital processing methods. The essential SAR image quality assessments are spatial resolutions, Integrated Sidelobe Ratio (ISLR) and Peak Sidelobe Ratio (PSLR). READ MORE
