Preserved Fulltext
In this paper, we investigate the joint design of a transmit beampattern and angular waveform (AW) for colocated multiple-input multiple-output (MIMO) radars. ...
The two models can be unified into the same framework, and an efficient algorithm is proposed to solve the problem under a constant modulus constraint. ...
However, for colocated MIMO radars, the transmit beampattern of nearly orthogonal waveforms is omnidirectional, which has a low transmit gain and is more suitable for search modes or acquiring surrounding ...
