Efficient signal processing in MIMO radars

An efficient way to process data of MIMO radars by means of FFT is here discussed. However, MIMO radars are here shown to suffer a discontinuous phase history across all the channels, due to their geometry, especially in the short-range. In turn, this would prevent the FFT-based algorithm to work co...

Zusammenfassung:An efficient way to process data of MIMO radars by means of FFT is here discussed. However, MIMO radars are here shown to suffer a discontinuous phase history across all the channels, due to their geometry, especially in the short-range. In turn, this would prevent the FFT-based algorithm to work correctly. Consequently, it is here shown that data of MIMO radars have to be pre-processed in order to allow an efficient FFT-based localization. For this purpose a sub-optimal algorithm is presented, discussed and tested against real data gathered by the JRC MIMO radar system.
