Antenna array for Ku band
Prouza, Jakub ; Mikulášek, Tomáš (referee) ; Raida, Zbyněk (advisor)
This diploma thesis deals with the selection of antenna elements suitable for use in an ultra-wide band antenna array for radar applications. The selection is followed by the design and measurement of a prototype. The realized gain of the whole structure, the main beam width and the possibility of electronic beamforming in the horizontal plane are the most important parameters of the designed antenna array. The numerical model of the selected antenna element was developed, and parameters were verified to exploit the element in the antenna array. Afterwards, the array was created as a numerical model. Results produced by simulations were verified by measuring the prototype subsequently.

Radar Signal Processing for Radio Altimeter
Krasňanský, Milan ; Maršík, Lukáš (referee) ; Zemčík, Pavel (advisor)
Táto diplomová práca sa zaoberá návrhom a implementáciou algoritmu pre spracovaniu signálu z radaru využívajúceho frekvenčne modulovanú kontinuálnu vlnu. Cieľom je implementácia algoritmu, ktorý by bol dostatočne rýchly (výpočet v reálnom čase na cieľovej platforme) a dostatočne presný pre použitie v rádiovýškomere v ľahkom lietadle so zameraním na použitie počas pristávacieho manévru. Hlavnou metódou spracovania signálu, použitou v implementácii, je Diskrétna Fourierova transformácia. Vytvorený algoritmus bol otestovaný na reálnych letových dátach a pre pristávací manéver dosiahol uspokojivé výsledky.

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.

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.

Environment mapping
Mohorko, Martin ; Pavlík, Jan (referee) ; Bilík, Martin (advisor)
This bachelor thesis deals with the description of possible ways of mapping the unknown environment, which could be in this case both environments - aerial and terrestrial. It is focused on mapping by radars and 3D scanners, through their history, distribution, scanning methods, methods of displaying data or description of output data to their practical application. Furthermore based on selected criteria, methods were compared and it was explained why and which method is preferable than the other one. There is also in this work mention of other methods used for environment mapping of today and their use and potential for several future applications. In the conclusion was outlined the possible use concept on the radar locating system in connection with the 3D scanner.

Význam a organizování služby pátrání a záchrany v civilním letectví
Albastová, Slavěna ; Balážová, Renáta (referee) ; Chlebek, Jiří (advisor)
A comprehensive survey including concise attributes of methods and procedures being used during search and rescue operations on the territory of the Czech republic are the main purpose of this bachelor thesis. The search and rescue operations create one part of commitments resulting from the membership of the Czech republic in the ICAO International Civil Aviation Organization. This thesis is regarded as a study guide for future professional pilots obliged to get through their examination of ÚCL (Úřad civilního letectví).
