Abstract: A new concept of the two-dimensional (2-D) Butler Matrix (BM) is proposed for 2-D beam steering of a 2-D planar array. An example of a 16×16 BM for a 4×4 planar array is presented. All phase ...
Some accepted solutions fail on certain edge cases because they don’t properly handle arrays where all elements are the same or where negative numbers are included. These cases are not covered in the ...
Abstract: Among various sensor array configurations, the L-shaped nested array offers improved performance for 2-D direction-of-arrival (DOA) estimation through co-array processing. However, ...
