The automotive radars are significantly drifting towards the 77GHz electromagnetic spectrum band, and by 2020, they will no longer operate in the 24GHz band as per the regulations given by the European Telecommunications Standards Institute (ETSI) and Federal Communications Commission (FCC) in Europe and the U.S. With the communication systems also heaping towards the magnitude of radar functionality, the 77GHz spectrum has opened a broad scope and possibility to combine both communication and radar waveforms and offer joint radar sensing and communication functionality.The true aim of this thesis work is to implement one of the widely used digital modulation techniques namely binary phase shift keying to embed information bits in the frequency modulated continuous radar waveform (FMCW) via a microcontroller (MCU) to facilitate real-time radar processing and information exchange.The report starts with presenting a theoretical overview on FMCW automotive radar, waveforms for both sensing and communication and a brief review on the MCU's in the automotive radars. The next chapter of the report gives a detailed explanation of the hardware and software architectures on which the thesis implementation is carried out. The following chapter of the report focuses on the main adopted implementation to embed information bits and all the underlying methodologies related to it. Finally, the results of this thesis work are diversified into obtaining real-time 2D fast Fourier transform (FFT) range/doppler spectrum and beat signals, to perform reconstruction of the message embedded in the FMCW waveform and to validate the correctness of the phase coding.
