1. 1. FMCW mmWave Radar for Detection of Pulse, Breathing and Fall within Home Care

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Axel Trange; [2021]
   Keywords : ;

   Abstract : Countless of elderly people fall and get hurt within their homes, worldwide, every year, and as they can not always reach out for help themselves, they end up helplessly waiting for someone to notice what has occurred. Throughout this work, it is investigated if remote sensing of the mmWave FMCW radar IWR6843AOPEVM can be adopted to detect the incident of falls, and also detect the vital signs of the human subject.

3. 2. Estimation of Aerodynamic Parameters in Real-Time : Implementation and Comparison of a Sequential Frequency Domain Method and a Batch Method

   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Lina Nyman; [2016]
   Keywords : Aerodynamic coefficients; least squares; chirp z-transform; instrumental variables; missing data;

   Abstract : The flight testing and evaluation of collected data must be efficient during intensive flight-test programs such as the ones conducted during development of new aircraft. The aim of this thesis has thus been to produce a first version of an aerodynamic derivative estimation program that is to be used during real-time flight tests. READ MORE

4. 3. Real-Time Estimation of Aerodynamic Parameters

   University essay from Linköpings universitet/Reglerteknik

   Author : Sofia Larsson Cahlin; [2016]
   Keywords : Least squares; Chirp z-transform; Instrumental variables; Missing data;

   Abstract : Extensive testing is performed when a new aircraft is developed. Flight testing is costly and time consuming but there are aspects of the process that can be made more efficient. READ MORE

5. 4. Antenna elements matching : time-domain analysis

   University essay from Akademin för teknik och miljö; Avdelningen för elektronik, matematik och naturvetenskap

   Author : Cristina Condori-Arapa; [2010]
   Keywords : Time-domain analysis; Chirp z-transform; Kaiser-Bessel window; Filtering in time domain; Effects of time-domain analysis; Reverse engineering; De-embedding; TRL algorithm; uncertainties; sensitivity;

   Abstract : Time domain analysis in vector network analyzers (VNAs) is a method to represent the frequency response, stated by the S-parameters, in time domain with apparent high resolution. Among other utilities time domain option from Agilent allows to measure microwave devices into a specific frequency range and down till DC as well with the two time domain mode: band-pass and low-pass mode.
