Sistem za merjenje hitrosti z Dopplerjevim radarjem

ORAŽEM, MIHA (author), Bulić, Patricio (mentor)

Namen diplomske naloge je razvoj sistema, ki s pomočjo Dopplerjevega radarja meri hitrost avtomobilov. Sistem je ustvarjen z razvojno ploščo STM32F4 Discovery in Dopplerjevim radarskim modulom RFBeam K-MC1. Pri tem je razvita še testna aplikacija, ki nam omogoča testiranje algoritma in parametrov, ki se uporabljajo za izračun hitrosti. Program za mikrokrmilnik je spisan v programskem jeziku C. Testna aplikacija je spisana v programskem jeziku C++ in za uporabniški vmesnik uporablja knjižnico QT. Diplomska naloga predstavi Dopplerjev pojav, na katerem temelji Dopplerjev radar. Predstavi tudi Fourierjevo transformacijo za obdelavo signala, dobljenega iz radarskega modula. Nadalje je opisan še razvoj testne aplikacije ter programa za mikrokrmilnik.

Abstract

The purpose of this thesis is to develop a system that measures the speed of passing cars using the Doppler radar. The system was created with an STM32F4 Discovery development board and the RFBeam K-MC1 Doppler radar module. An application, that enables testing of the algorithm and parameters, used for speed computation, has also been developed. The program for the microcontroller is written in the C programming language. The testing application is written in C++ programming language and uses the QT framework for the graphical user interface. The thesis explains the Doppler Effect, which is the foundation for the Doppler radar. It also explains Fourier transform used for analyzing the signal, acquired from the radar module. The last part of the thesis describes the process of developing the test application and the program for the microcontroller.
