Abstract
The direct space-to-information converter (DSIC) unifies conventional delay-and-sum analog conventional beam- forming (CBF) with compressive sampling (CS) rapid direction-of-arrival (DOA) finding into a single, reconfigurable phased-array receiver architecture. Where current CBF-based DOA scanners need to exhaustively search through multiple DOA angles, the DSIC is able to receive energy from all possible angles by modulating its antenna weights psuedo-randomly. The DSIC RF-ASIC can operate from 1
