Abstract

Current waveform optimization for colocated Multiple-Input Multiple-Output (MIMO) radar focuses on pulsed radar. In this paper, we study waveform design for continuous waveform MIMO radar that steers transmit beams toward different directions in a time-division mode. A waveform design criterion is formulated, which tends to fit a given transmit beampattern and to suppress auto/mutual correlation sidelobes of angular waveforms illuminated into different spatial directions. Numerical results are given for transmit beampatterns with one and two peaks to verify the effectiveness of the waveform design criterion. Different from pulsed-radar, angular waveforms associated with continuous-waveform MIMO radar does not bear a bell outline.
