This thesis presents the design and implementation of a multifunctional radar sensor. Utilising microstrip transmission line technology, a front-end receiver has been designed based upon a six-port architecture. Additionally, digital signal processing has been implemented on a microcontroller, enabling processing and extraction of information from the down converted quadrature signals. Results have show that the sensor is capable of operating as both a continuous wave radar and frequency modulated continuous wave radar. Through measurements, it has been established that the sensor is capable of wireless measurements, such as vital signs and vibrations. Furthermore, a graphical user interface has been design, allowing a way of switching between different radar configurations and the presentation of measured data to the user.
