Beampattern Synthesis With Virtual Covariance Matrix and Response Control Vector Design

This letter presents the minimized ripple array pattern control (MRAPC) algorithm to realize beampattern synthesis. Inspired by adaptive array theory, the virtual normalized interference-plus-noise covariance matrix is constructed to realize sidelobe suppression, and the response control vector is designed to shape the mainlobe. The minimum array response variation principle is introduced to solve response control problems, and the designed weights are obtained in closed-form. Considering the mainlobe ripple term, an efficient scheme is presented to realize beampattern synthesis with less response deviation. Simulation results validate the effectiveness and efficiency of the MRAPC algorithm for precise array response control and beampattern synthesis.
