Radar Detection of Vital Signs
Köteleš, Dávid ; Zemčík, Pavel (referee) ; Maršík, Lukáš (advisor)
Nowadays, it is very important to measure the vital signs of a person. Thanks to the data that we get from measure, we can control health of the person. It is usefull as well in sports, where we can control performance of sportsman. Different technologies are used for measurement. We can divide these technologies in contact and contactless methods. Contact methods have their disadvantage and that one is when patient can not feel comfortable and then the results may not be correct. Thats why we are currently using contactless methods that we try to develop to achiev highest possible accuracy. In this work are signal processing strategies using fast fourier transform and different filtration techniques for monitoring vital signs described using radar device and eventually their variatons. These strategies are then tested on real data and compared to achiev best result. The IWR1642Boost and Texas Instruments demo software is used for practical exploration.
Smart Tramway in Brno
Fiala, Jan ; Maršík, Lukáš (referee) ; Zemčík, Pavel (advisor)
The goal of this thesis is selecting appropriate technologies, that can be used to locate tram while passing through a section where the pantograph should be lowered or raised, design and implementation of localization system. In this solution, radio frequency identification is used as main source of localization, distance from given place is determined by satellite navigation which is used as backup source of localization. The core of the system is the Arduino platform.
Mechanical/Physical Simulation of Solid Objects
Bureš, Jaroslav ; Maršík, Lukáš (referee) ; Široký, Adam (advisor)
This work deals with simulation of launching a golf ball. Here are described simulation techniques which can be used for computer simulations. In addition, physical laws are discussed, that need to be understood to create a valid golf ball launch model. These include aerodynamic laws for calculating ball's flight trajectory, as well as events occurring while ball moves on the ground. After this is analyzed implementation of the program using C++ and OpenGL graphics library. The work is completed with comparison of measured simulation results with analytical solution and values of other applications.
Terrain Photographing from an Aircraft
Skočdopole, Jan ; Maršík, Lukáš (referee) ; Široký, Adam (advisor)
This thesis deals with terrain photography from an aircraft. Subject of solution includes phases of planning and preparation of flight, navigation, taking images and telemetry recording. For this purpose remote camera placed under planes hull and tablet with application placed in the cockpit are used.
Radar Active Cruise Control
Rous, Petr ; Široký, Adam (referee) ; Maršík, Lukáš (advisor)
This bachelor thesis is dedicated to radar active cruise control. The aim of the work is to implement program logic of the adaptive cruise control system. It describes basic techniques of radar signal processing as well as various difficulties during this process. It is also concerned with methods used for radar objects detection. Withing the work, two different radar modules are compared for their suitability to use as sensors of active cruise control. Finally, implemented system is tested using data collected in real road transport.
Radar Altimeter for Ultralight Aircraft
Zahradník, Jiří ; Zemčík, Pavel (referee) ; Maršík, Lukáš (advisor)
In this bachelor thesis author designs a radar altimeter. In this thesis the emphasis is placed onto modular architecture and that is why this altimeter is designed as a group of independent modules communicating through BSD sockets. Software implementation is made in C++ and for sound generator is used library PulseAudio. Next topic is multithreading safety implementation of queue and stack which was made by template class to keep simplicity and generality.
Security System for Regional Train Routes
Pitřík, Martin ; Maršík, Lukáš (referee) ; Musil, Martin (advisor)
This project describes design, implementation and testing of security system for regional train routes. Project includes design and implementation of hardware, firmware, communication interface and software. Design is focused on simplicity and low installation costs, while all possibilities of modern security systems remains preserved. 
Radar Signal Diffusion Simulator
Ormoš, Michal ; Zemčík, Pavel (referee) ; Maršík, Lukáš (advisor)
Aim of this paper as the title suggest is creating radar simulator, which is capable of build up whole process of capturing broadcasting signal. From radar broadcasting, through his simple rebound from object up to capturing the returning signal back to radar. All this in virtual environment.The problem was solved in Matlab programming environment, in a manner of simulation of three dimensional area, which contains arbitrarily moving points. The points represent radar and object on which is radar aiming. Within the environment we are calculating, obtaining and processing all necessary data. From distance, angles to calculations of frequency and power of returning signal.The result of this work is full-valued simulated environment, which demonstrate whole process of capturing moving object by radar to display it in spectogram, which contains information about object passing the radar. Output is raw signal responded to Doppler shift, emerging in simulated environment. Simulator serve for creating the early concept.
Speed Measuring of Vehicles Using Radar
Novák, Adrián ; Široký, Adam (referee) ; Maršík, Lukáš (advisor)
This thesis focuses on the process of creating a desktop application that processes radar data, from which it detects vehicles, their speed, and direction in an appropriate manner.The core of the application uses a Fourier transformation to transform radar data from time to a frequency domain. This frequency spectrum is used to get the important informationfor the calculation of vehicle speed, followed by a correction of the calculation by the cosine factor. The result of this thesis is a desktop application, which allows its user to obtain information from radar data about the detected vehicle and subsequently, to determine its speed.
Radar-Based Measurement for Speed Disciplines
Piňos, Michal ; Široký, Adam (referee) ; Maršík, Lukáš (advisor)
The aim of this bachelor thesis is radar-based measurement for speed disciplines. For this purpose, the Doppler radar with continuous wave was used, K-MC4 to be specific. Standard signal processing techniques were used to extract the speed information from the radar signal. The key method for obtaining Doppler frequency from signal is Fourier transform. Cosine effect is compensated based on the computed angle.The result of this work is a detector capable of measuring speed and direction of measured objects. Implemented solution also allows the detection of certain objects.
