  1. 1. Direct Signal Interference Suppression and Target Detection for Low-Cost SDR-Based Passive Bistatic Radar

    University essay from Linköpings universitet/Reglerteknik

    Author : Oskar Jonsson; [2022]
    Keywords : passive radar; ECA; LMS; software-defined radio;

    Abstract : Passive radar is a technology for detection of targets using echoes of existing radio transmitter, such as FM-radio. Since only receivers are needed for operation, a passive radar system has the possibility of being implemented using low-cost hardware. READ MORE

  3. 2. 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

  4. 3. Clutter Removal in Single Radar Sensor Reflection Data via Digital Signal Processing

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Mohammadreza Kazemisaber; [2020]
    Keywords : Surveillance Radar; Ultra-Wideband Radar; Clutter Reduction; FMCW radar; Digital signal processing; Moving target detection; Doppler Processing.;

    Abstract : Due to recent improvements, robots are more applicable in factories and various production lines where smoke, fog, dust, and steam are inevitable. Despite their advantages, robots introduce new safety requirements when combined with humans. READ MORE

  5. 4. 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

  6. 5. 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
