Detection Performance of Noncoherent Radar: MIMO Radar, Phased Array Radar, Directional MIMO Radar
The Journal of Korean Institute of Communications and Information Sciences, 2011 In a traditional phased array radar, closely spaced antenna elements transmit a scaled version of single waveform to maximize the signal energy. On the contrary, a multiple-input multiple-output (MIMO) radar consists of widely separated antennas and transmits an arbitrary waveform from each antenna element.
