  1. 1. Development of an underwaterruler using an AUV-deployedbeacon and Matched filter CFARdetector

    Master-uppsats, KTH/Marina system

    Författare :Yaolin Ge; [2020]
    Nyckelord :;

    Sammanfattning : Our ocean covers more than 70% of our planet’s surface. It is a huge reservoir continuously supplying us with enormousvaluable resources. The autonomous aquaculture, deep sea mining, subsea oil / gas exploitation and marine biology etc.,are the increasingly important driving forces for the development of underwater robotics. LÄS MER

  3. 2. Wall Compensation Algorithms for M-sequence UWB Radar

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Mhd Jihad Abou Raas; [2016]
    Nyckelord :Ultra-wideband UWB ; Wall Compensation Algorithms;

    Sammanfattning : A technique for wall compensation in the ultra-wideband (UWB) through-wall imaging radar is presented. The UWB system can be utilize in high precision measurements, but due to phase distortion and amplitude attenuation caused by the wall the precision is limited, the target is displaced, and the image is defocused.

  4. 3. Global Backprojection for Imaging of Targets Using M-sequence UWB radar system

    Master-uppsats, Akademin för teknik och miljö

    Författare :Madhava Reddy Kota; Binod Shrestha; [2013]
    Nyckelord :: Synthetic Aperture Radar; Time domain algorithm; Back projection algorithm; Ultra Wide-beam; M-sequence; SAR Image processing; UWB radars with M-sequence.;

    Sammanfattning : Synthetic Aperture Radar (SAR) is an emerging technique in remote sensing. The technology is capable of producing high-resolution images of the earth surface in all-weather conditions. LÄS MER

  5. 4. DETECTION OF MULTIPLE TARGETS USING ULTRA-WIDEBAND RADAR

    Master-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Shoaib Amin; Imran Mehmood; [2011]
    Nyckelord :M sequence UWB radar; Multiple target detection; UWB radar;

    Sammanfattning : In recent years, ultra-wideband (UWB) radars are gaining popularity in the radar field mainly inindustrial and commercial areas. The UWB radar has the potential of dramatically improving thecontrol and surveillance of industrial processes in confined areas. LÄS MER

  7. 5. Dispersion Effects on OCDMA System Performance

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Författare :Abdul Gafur; [2009]
    Nyckelord :OCDMA; MAI; SIK; ROP; WDM; PRNG;

    Sammanfattning : This thesis presents the effect of dispersion and Multi Access Interference (MAI) of optical fiber on the Bit Error Rate (BER) performance of a Direct Sequence Optical Code Division Multiple Access (DS-OCDMA) network by means of intensity modulation and optical receiver correlators. By using Matlab simulations, Signal-to-Noise Ratio (SNR) versus Received Optical Power (ROP) of an OCDMA transmission system can be evaluated with a so-called 7-chip m-sequence for different numbers of system users.
