WebJan 27, 2024 · The popular semidefinite relaxation (SDR) technique is employed to solve the resulting non-convex problem, and the tightness of SDR is discussed. Further, we propose to incorporate an extra constraint of main beam control into the problem to achieve a flat magnitude response of the beampattern over the ROI. WebOct 22, 2024 · It is well known that semidefinite programs (SDPs) can be solved by interior point methods (IPM) in polynomial time. Also many real world experiments have resulted that semidefinite relaxation (SDR) is an efficient method in providing accurate (and sometimes near-optimal) approximations.
