Sub-Nyquist Radar Systems: Temporal, Spectral and Spatial Compression [PDF]
, 2018 Conventional radar transmits electromagnetic waves towards the targets of interest. In between the outgoing pulses, the radar measures the signal reflected from the targets to determine their presence, range, velocity and other characteristics. Radar systems face multiple challenges, generating many trade-offs such as bandwidth versus range resolution ...
