Riassunto analitico
The aim of this master thesis, whose activities have been accomplished
in cooperation with CNH Industrial Modena, is to investigate the use of
a 77 GHz MIMO FMCW radar and the compensation of its non-idealities, and
to devise signal processing algorithms for range estimation. The main
contributions provided by this thesis can be summarized as follows. As
far as the radar use is concerned, a software toolchain allowing us to
easily manage the radar output is developed, and a simple technique for
mitigating the effect of direct coupling between distinct antennas of
the radar array is derived and tested. Moreover, the exploitation of the
virtual concept to create a virtual antenna array wider than than the
physically available array is analysed. The developed work on range
estimation, instead, concerns the development of an accurate frequency
estimation method based on the use of fast Fourier transform and
iterative cancellation in the frequency domain. The accuracy of the
proposed estimation method is assessed by means of computer simulations.
