Phase compensation and processing in multiple-input–multiple-output radars

open access: yesIET Radar, Sonar & Navigation, 2012
In this study, the issue of phase discontinuity in multiple-input-multiple-output (MIMO) radar systems is analysed and described in detail, together with an efficient way for processing MIMO radar data by means of discrete-time Fourier transform (DFT) fast Fourier transform (FFT). In particular, here it is shown that the phase history of a point target
