Abstract

This work investigates on the performance improvements in terms of sidelobe reduction provided by arrays organized into randomly overlapped subarrays (ROSAs) in comparison to other subarray arrangements such as contiguous and uniformly-overlapped modules. This configuration can be advantageous for applications that need to scan over a limited angular sector. The performance of the ROSA design is thoroughly analyzed for different degrees of overlapping in terms of scan losses, minimization of peak side lobe level, number of components and array size.
