Transmit beamspace design for direction finding in colocated MIMO radar with arbitrary receive array
14 years 10 months ago
The transmit beamspace design problem for colocated multiple-input multiple-output (MIMO) radar is considered. We show that the MIMO radar transmit beampattern can be designed so ...
