ABSTRACT

The progress in resolution of automotive radar sensors involves a considerable increase in data-rate and computational throughput. Dedicated processing architectures have to be investigated in order to manage the tremendous amount of data. This chapter presents a FPGA-based signal processing architecture capable of handling 16 parallel MIMO radar receiving channels with a sampling frequency of 250 MHz each. The usage of frequency-modulated continuous-wave radar sensors can be advantageous in short range applications, especially due to their high range resolution capability and much lower peak power requirements. The detection space has to be scanned individually, i.e. each possible direction of arrival will be measured separately. An alternative to a mechanical steered antenna is the use of an antenna array, where each antenna element is fed by a time delayed version of the transmit signal.
