Vehicle sensoric systems
Altal, Rami ; Kovanda, Jan (advisor) ; Zewdie, Retta (referee)
The objective of the thesis is to analyze modern sensoric systems and assistance systems of active vehicle safety. In the beginning of the thesis it describes the working principles of individual sensors, their structures and their potential for driver assistance systems and in the following chapter it describes in detail some of the selected modern assistance systems. The final chapter describes the experiment, a simulation of adaptive cruise control function using the Lego Mindstorms NXT programmable robotics kit.

Speed Measurement Using Radar
Andrla, Jiří ; Široký, Adam (referee) ; Maršík, Lukáš (advisor)
The principal goal of this bachelor thesis is to design a program in the Matlab programming language that measures the speed of vehicles scanned by a radar. In this thesis, the program is also implemented in the C++ programming language. The designed software detects moving vehicles in sets of data obtained from a CW radar. For each of these vehicles, their speed is computed with respect to the angle of their motion to the orientation of the measuring device. In the end, overall statistics are generated from the data gained. The thesis solves the problems of correction of the speed measurement based on the measuring angle. This technique should provide better results than other classical methods without the correction. The outcome of this thesis can be interesting for every application or system that uses speed measurement with a radar under different angles.

Radar-Based Speed Measurement of Sport Projectiles
Bezděk, David ; Široký, Adam (referee) ; Maršík, Lukáš (advisor)
This bachelor's thesis deals with a proposal and implementation of application, that extracts speed information of sport projectiles from radar data. Firstly, there is description of radar, Doppler's effect and especially continuous-wave radar. Then the bachelor’s thesis continues with signal processing issues, after which speed can be calculated.In next part there is a describtion of collecting real data and their evaluation. In the last part there is a summary of the thesis, eventual use of the application and it's possible extensions.

Computer design of primary surveillance radar siting on airport
Krajíček, Antonín ; Urbanec, Tomáš (referee) ; Láčík, Jaroslav (advisor)
This semestral thesis deals with the application of the principles of site selection for surveillance radar designed for air traffic control in MATLAB. The thesis describes processing of maps and implementation of waypoints for air traffic control support. Another objective is to create a script for the calculation of the radar range by using the Radar Equation. The thesis concludes with addressing the issue of radio wave propagation over irregular terrain using the Split-step parabolic Equation.

Robocar - The Autonomous Driving
Hnát, Miroslav ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
In my Bachelor thesis I deal with automated car driving requirements. First I make the real plan and select the correct software tool for simulation and realization this issues. Second I solve model for autonomous car driving simulation, breaking and rotation wheels. There is open area with several obstacles in simulation conditions. I define possibly errors and I recommend its solution. Next very important part of my thesis are identify the parameters of real vehicle and verification the correctness of model by simulation test. I review variances from model. The object of this has to check reactions of the real system. Whole solution will be implemented into individual components. The individual components will be then compared with simulation results. In conclusion I will appreciate achieved results and recommend my solutions.

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.

Radar-Based Speed Measurement for Sport Events
Radoš, Daniel ; Polok, Lukáš (referee) ; Maršík, Lukáš (advisor)
The Bachelor thesis is dedicated to speed measurement focused on sport events. In introduction of this thesis, basic principles of radar and their dividing are mentioned. Following part of thesis is dedicated to continuous wave radar, using Doppler effect and also principle of sequential signal processing, followed by resultant speed calculation of measured object. Ultimately, selected methods are implemented and tested using real data. In the end, the implemented application is evaluated and the possible continuation of this work is stated.
