— This paper presents a new approach for receiver steered antenna thinning using a digitally assisted Mills cross array architecture. First, we derive the power patterns of an M × N element planar rectangular array of isotropic radiators. In the next step, we replicate these power patterns using two implementation approaches which result in digitally assisted Mills cross arrays. The first approach used a multiplication block, while the second approach used a convolution block, both in the digital domain. The power patterns of a 121 element 30 dB Dolph-Chebyshev uniform rectangular array are recreated using 41 and 21 elements respectively by the techniques we propose. Simulated results, verifying the theoretical findings, are presented and discussed.
