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 Altimeter for Ultramicro Airplanes
Imrich, Marek ; Maršík, Lukáš (referee) ; Zemčík, Pavel (advisor)
Radar equipment is an integral part of the aviation sector. It is very important to use a suitable module to guide ultralight aircraft during landing. The bachelor thesis is focused on the use of altitude radar based on the microwave sensor IWR6843ISK manufactured by TEXAS Instruments and its application in practice for ultralight aircraft. Its ability in conjunction with a computer is the altitude guidance of an ultralight aircraft to the runway by generating sound tones to indicate to the pilot the distance above the terrain. The main goal of this work is to design a model for the use of a microwave module in conjunction with a computer and its subsequent testing of the suitability for use in performing a landing maneuver. The aim of this work is to design a system that works with millimeter radar and its evaluation of usability in practice. The proposed module generates point clouds, which are then parsed, then the output data are suitably correlated, further transformed to the exact height of the aircraft above the terrain with subsequent sound interpretation to the pilot.

3D object detection from pointcloud
Červený, Patrik ; Richter, Miloslav (referee) ; Zemčík, Tomáš (advisor)
The bachelor thesis deals with the detection of 3D objects in a point cloud acquired by a LIDAR sensor. The thesis describes the sensors that collect the data for the point cloud, the methods to process the data and the final representation of the collected data, using the chosen application. By using a LIDAR sensor we detect a 3D image of the point cloud at the railway stations in Brno and with the help of the available methods for processing and application we try to describe what the sensor shows us through the data.

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.

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.

Radar sensors for speed measurements
Doležal, Tomáš ; PhD, Jaroslav Čechák, (referee) ; Kokolia, Martin (advisor)
The main topic of this bachelor thesis is selecting a suitable microwave sensor for measuring the speed of vehicles in regular traffic, while covering multiple road lanes by a suitable method. Furthermore, the optimal one is selected in the form of search, based on the necessary parameters from commercially available radar sensors measuring primary speed. In the next step, simulation is performed for the selected speed sensor in the MATLAB environment, depending on its parameters and the modes in which it can work. The simulation also includes environmental influences on the received signal. There is introduced programmed graphical user interface for simulating a lot of situations on the road for two cars in the next section. Last section summarizes results of real measurement.

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.

Speed Measuring of Vehicles Using Radar
Vlkovič, Vladimír ; Široký, Adam (referee) ; Maršík, Lukáš (advisor)
This masters thesis is focused around the designing and implementation of an anpplication that can extract information on speed of vehicles from radar data. The radar measurements were done by using a continous wave radar. The emphasis is placed on the computation of the angle in which the car approaches the radar and on the speed correction based on this angle. The final design was implemented in Matlab. The evaluation of the implemented solution was done on reference data.
