Low Sidelobe Sparse Concentric Ring Arrays Optimization Using Modified GA
International Journal of Antennas and Propagation, 2015 To minimize the peak sidelobe level (PSLL) of sparse concentric ring arrays, this paper presents an optimization method of grid ring radii of these arrays. The proposed method is based on modified real genetic algorithm (MGA); it makes grid ring radii as

Colocated MIMO Radar Waveform-Array Joint Optimization for Sparse Array
Sensors, 2023 Colocated multiple-input multiple-output (MIMO) radar can transmit a group of distinct waveforms via its colocated transmit antennas and the waveform diversity leads to several advantages in contrast to conventional phased-array radar. The performance depends highly on the degrees available, and element spacing can be deemed as another source of ...
