Astronomers have just solved a long-standing mystery about a rare, rapidly spinning neutron star known as PSR J1023+0038.

A novel two-stage phase shifter phased array architecture is proposed, coupling subarray division with mixed-resolution phase shifters to reduce costs while ensuring the beam performance. The ...

Abstract: A sparse array synthesis algorithm for phased array scanning radar using reweighted L1 -norm minimization approach is proposed in this paper. The algorithm aims to ensure the beampattern is ...
