Robust transmit beampattern matching synthesis for MIMO radar

A robust transmit beampattern matching synthesis approach is described for a multiple‐input and multiple‐output radar with manifold vectors perturbation. This synthesis technique minimises the worst‐case matching performance between the transmit beampattern and the desired beampattern (in a least absolute deviations sense), through designing the waveform covariance matrix. Also, the resulting minimax problem can be translated into a convex problem is showed. Finally, simulation results verify good performance of the proposed robust transmit beampattern synthesis approach.
