2. 1. Signal Processing for Radar with Array Antennas and for Radar with Micro-Doppler Measurements

   University dissertation from Karlskrona : Blekinge Tekniska Högskola

   Author : Svante Björklund; Blekinge Tekniska Högskola.; [2017]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radar; signal processing; array antenna; subarray; clutter; jamming; interference; direction of arrival estimation; security; micro-Doppler; feature extraction; classification;

   Abstract : Radar (RAdio Detection And Ranging) uses radio waves to detect the presence of a target and measure its position and other properties. This sensor has found many civilian and military applications due to advantages such as possible large surveillance areas and operation day and night and in all weather. READ MORE

4. 2. High-resolution meteor exploration with tristatic radar methods

   University dissertation from Umeå : Fysik

   Author : Johan Kero; Umeå universitet.; [2008]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; meteors; meteoroids; interplanetary dust; radar; head echoes; ablation; meteoroid fragmentation; radar; huvudekon; ablation; meteorisk fragmentation; meteorer; meteoroider; interplanetärt stoft; TECHNOLOGY Other technology Space engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Rymdteknik;

   Abstract : A meteor observed with the naked eye is colloquially called a shooting star. The streak of light is generated by an extra-terrestrial particle, a meteoroid, entering the Earth’s atmosphere. The term meteor includes both luminosity detectable by optical means and ionization detectable by radar. READ MORE

5. 3. Analysis of Resistor-Loaded Bow-Tie Antennas for Ground Penetrating Radar Applications

   University dissertation from Stockholm : Alfvénlaboratoriet

   Author : Disala Uduwawala; KTH.; [2004]
   Keywords : Ground penetrating radar; Buried object detection; Simulation; Radar antennas; Radar signal processing; FDTD methods; Optimal design; Lossy media; Dispersive media; Clutter; Polarization;

   Abstract : Ground penetrating radar (GPR) systems are increasinglybeing used for the detection and location of buried objectswithin the upper regions of the earth's surface. Numericalsimulation of such systems plays an important role in thedevelopment of GPR hardware and signal processingtechniques. READ MORE

6. 4. Radar Probing of the Sun

   University dissertation from Uppsala : Acta Universitatis Upsaliensis

   Author : Mykola Khotyaintsev; Uppsala universitet.; [2006]
   Keywords : Space and plasma physics; solar radar; active experiments; space physics; solar corona; plasma; Rymd- och plasmafysik;

   Abstract : This thesis is dedicated to the theory of solar radar experiments. The Sun exhibits a variety of interesting and complicated physical phenomena, examined mainly through analysis of its radiation. Active solar probing by radar provides an alternative possibility to study the Sun. READ MORE

7. 5. Robust Transceiver Design and Waveform Synthesis for Wideband MIMO Radar

   University dissertation from Uppsala : Acta Universitatis Upsaliensis

   Author : Marie Ström; [2012]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wideband radar; Robust analysis; Interference; Waveform synthesis; Transmit–receive filter design; MIMO radar;

   Abstract : This thesis deals with the problem of designing and synthesizing waveforms that are optimal, both in a signal-to-noise-and-interference ratio (SNIR), and in a system hardware design perspective, i.e., to synthesize time domain waveforms with a low peak-to-average power ratio (PAPR), or even constant modulus.
