digital subarray model
Hi, all.
This post can probably be placed at antenna forum, but I think it is a DSP matter more than a RF/MW.
I'm interested in digital beamforming for radar phased arrays. When using narrowband signals, digital beamforming can be mainly achieved by FFT processing. But, what about wideband signals? And what happens if the array is very large and the digitization is performed at subarray level?
What kind of processing must/can be done? Beamspace processing?
Have any of you references (papers, books) about these situations (I mean, wideband radar with DBF at subarray level)?
Thanks in advance.
