Software Support for Project Definition with Using of Logical Frame Method
Viktorin, Martin ; Bartík, Vladimír (referee) ; Květoňová, Šárka (advisor)
The purpose of this work is to design and implement software support for Project Definition of LFM (Logical Frame Method). The first part is about project management and about necessity to use it for solving projects. There is description of phases of project and detailed description of logical frame method. In the second part there is system requirements analysis, description of the application via UML and implementation of application which was created in development environment Microsoft Visual Studio 2005 in C# language. There is a short summary, possible extensions and comparing with existing applications in the end of the work.
Radar Altimeter for Ultralight Aircraft
Absolon, Marek ; Zemčík, Pavel (referee) ; Maršík, Lukáš (advisor)
The main topic of this paper is a radar ranging for use in an aircraft altitude measurement. This should help beginner pilots in practicing landing and take off.   To achieve this aim, we chose to use continuous-wave radars with frequency modulation (FMCW). Our solution is based on linear frequency modulation method using triangular modulation pattern.   During the testing, it was found out, that radars with 24 GHz bandwidth have a range resolution from 1 meter (depending on modulation depth) to 13 metres. This range is sufficient for usage in training of takeoffs and landings, which is the real purpose of this paper. Another good finding is, that during takeoff and landing, there is minimal occurrence of doppler frequencies.   Final algorithm works on principle of two currently processed spectrums, which are substracted. Afterwards, found peaks are validated on current spectrum.

WLFM radar signal ambiquity function optimalization using genetic algorithm
Bartoš, M.
This paper deals with optimization of ambiguity function. The purpose of article is to describe optimization process using Genetic Algorithm for suppressing side-lobes of a signal. There are also depicted properties of weighted linear frequency modulation waveform.
