英文摘要	Wideband constant beamwidth beamforming is one of the key technologies achieving low probability of intercept (LPI) performance in the area of array signal processing. In this paper, based on MIMO radar signals, firstly, two approaches are proposed to synthesise the power spectral density matrix (PSDM) to approximate given beampatterns. Then, both proposed approaches are converted into the second-order cone programming (SOCP) problems by introducing new variables. Finally, the minimum points of the new cost functions are solved by the convex optimisation toolbox. Numerical simulation results show that the proposed approaches are effective compared with the existing wideband beampattern design approach; also, the designed beampatterns maintain a constant beamwidth across the entire frequency band. © Copyright 2016 Inderscience Enterprises Ltd.
