A low-complexity systolic-array architecture is proposed for obtaining multiple(N) broadband radio-frequency (RF) beams in smart antenna arrays. The N-beam 2D IIR digital filter is based on the concept of 2D passive ladder network resonance, leading to differential-form implementations which are highly-suitable for RF throughput levels. The proposed(More)
The software-defined radio (SDR) paradigm can be applied to radars. Novel radio-frequency (RF) chains and architectures can lead to enhanced radar schemes. After a brief review of SDR-based schemes, this work concentrates on the relevant topic of impulse-radio ultra-wideband (IR-UWB) radars. By emitting extremely-narrow impulses in time domain, these(More)
