Closed-Form Waveform Design for MIMO Radar Transmit Beampattern Synthesis via Integral Equality
IEEE Access, 2020 Recently, due to the adequate use of waveform diversity, MIMO technology has been widely adopted, resulting in the waveform design for MIMO radar beampattern synthesis becoming a hot issue. However, most previous works regarding this problem optimize the

Sparse Array Beampattern Synthesis via Majorization-Based ADMM [PDF]
2021 IEEE 94th Vehicular Technology Conference (VTC2021-Fall), 2021 Beampattern synthesis is a key problem in many wireless applications. With the increasing scale of MIMO antenna array, it is highly desired to conduct beampattern synthesis on a sparse array to reduce the power and hardware cost. In this paper, we consider conducting beampattern synthesis and sparse array construction jointly. In the formulated problem,
