  1. 1. Signal Processing for mmWave MIMO Radar

    University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Author : Óscar Faus García; [2015]
    Keywords : radar; automotive; MIMO; CW; 79 GHz; short-range radars SRR ; millimeter wave; CFAR; simulations; phase modulation; algorithms; system gain;

    Abstract : This thesis addresses the design study, implementation and analysis of signal processing algorithms for a 79 GHz millimeter-wave Phase Modulated Continuous Wave (PMCW) Multi Input Multi Output (MIMO) short range radar; performed in IMEC research institute (Leuven, Belgium). The radar system targets high resolution performance with low power consumption in order to integrate a full MIMO radar transceiver with digital processor and antennas in a compact package featuring a size of 1 cm2.

  3. 2. Miniaturized quadrature hybrid and rat race coupler utilizing coupled lines for LTE frequency bands

    University essay from Fysik och elektroteknik; Tekniska högskolan

    Author : Masiur Rahman; [2013]
    Keywords : Coupler; quadrature hybrid coupler; rat race coupler; LTE frequecy band; miniaturization; coupled line; microwave communication etc.;

    Abstract : Nowadays, demands for fully integrated and miniaturized RFIC (Radio Frequency Integrated Circuits) have increased in wireless microwave communication system. Passive components such as coupler, divider and filters are always fabricated in outside of ICs due to their bulky sizes, which have been a great barrier to a realization of a fully integrated design.

  4. 3. Design of Millimeter-wave SiGe Frequency Doubler and Output Buffer for Automotive Radar Applications

    University essay from Institutionen för systemteknik

    Author : Amjad Altaf; [2007]
    Keywords : Automotive Radar; VCO; Frequency Multiplier; SiGE; ACC; Millimeter-wave;

    Abstract : Automotive Radars have introduced various functions on automobiles for driver’s safety and comfort, as part of the Intelligent Transportation System (ITS) including Adaptive Cruise Control (ACC), collision warning or avoidance, blind spot surveillance and parking assistance. Although such radar systems with 24 GHz carrier frequency are already in use but due to some regulatory issues, recently a permanent band has been allocated at 77-81 GHz, allowing for long-term development of the radar service.
