DESIGN AND IMPLEMENTATION OF A DOPPLER-CAPABLE FMCW SHORT RANGE RADAR

This thesis presents a comprehensive study on the design and implementation of a frequency modulated continuous wave (FMCW) radar system. The study begins with an introduction to the principles of radar including the properties of electromagnetic waves, radar frequency bands, the structure of a radar and its equations. It then delves into the theory and operation of FMCW radar technology, exploring its advantages and signal processing techniques. The hardware components necessary for FMCW radar systems, such as transmitters, receivers, amplifiers, and microcontrollers, are thoroughly reviewed. The design process, including system specifications and architecture parameters, is clarified followed by a detailed analysis of both the hardware and software implementation method. The implementation phase describes the practical steps involved in building the hardware and software components of the radar system. This includes electronic circuit design, PCB layout, system assembly and test procedures for both the radar system and antennas designed in parallel. The development of the software includes signal processing algorithms, user interface design, system integration with reference to the challenges faced during the implementation process. Finally, performance evaluation includes experimental validation of the radar system, including transmit power, minimum detectable range, and other key metrics. Data analysis and interpretation of results lead to possible system improvements and extensions. In conclusion this thesis provides a comprehensive guide to understanding, designing and implementing FMCW radar systems.
