A hardware prototype of sub‐Nyquist radar with unknown pulses

Abstract In a conventional radar system, the hardware cost increases with the sampling rate of the receiver. Sub‐Nyquist radar systems operate at lower sampling rates and hence reduce the hardware cost and complexity. A sub‐Nyquist radar system uses the knowledge of the transmit pulse shape to deter...
