  1. 1. Adaptive clutter suppression in airborne surveillance radar

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Sabina Björk; [2021]
    Keywords : Clutter suppression; Radar; STAP;

    Abstract : Air- and spaceborne radars play an important role for civilian and military use. There are numerous applications such as earth observations, surveillance and others. High performance clutter suppression is a crucial part of many of these radar systems. READ MORE

  3. 2. Airborne Radar Ground Clutter Suppression Using Multitaper Spectrum Estimation & Choosing DPSS Parameters

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Carl-Henrik Hanquist; [2018]
    Keywords : DPSS; Multitaper; Radar;

    Abstract : One of the biggest challenges in any airborne radar is to distinguish a target from a strong ground echo. The main problem is that the ground echo, called ground clutter, can be up to a million times stronger than the response from the target in question. READ MORE

  4. 3. Airborne Radar Ground Clutter Suppression Using Multitaper Spectrum Estimation : Comparison with Traditional Method

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Linus Ekvall; [2018]
    Keywords : Ground clutter; tapering; multitaper; discrete prolate spheroidal sequences; minumum variance estimation; signal processing; radar; airborne radar;

    Abstract : During processing of data received by an airborne radar one of the issues is that the typical signal echo from the ground produces a large perturbation. Due to this perturbation it can be difficult to detect targets with low velocity or a low signal-to-noise ratio. READ MORE

  5. 4. Channel estimation in mobile wireless systems

    University essay from KTH/Signalbehandling

    Author : Pazi Alli Idd; [2012]
    Keywords : Time-variant channel; Discrete Prolate Spheroidal Sequences DPSS ;

    Abstract : The demands of multimedia services from mobile user equipment (UE) for achieving high data rate, high capacity and reliable communication in modern mobile wireless systems are continually ever-growing. As a consequence, several technologies, such as the Universal Mobile Telecommunications System (UMTS) and the 3rd Generation Partnership Project (3GPP), have been used to meet these challenges.
