Abstract
A system for Nyquist zone disambiguation of a received broadband RF signal is disclosed. The system includes continuous-wave (CW) and pulsed photonic sources whose outputs may be combined into a single input. Both CW and pulsed components of the combined photonic input are modulated by sampling the received RF input signal. The system includes hybrid couplers for IQ demodulation of the modulated combined photonic signal. The system demultiplexes the demodulated inphase and quadrature differential photonic signals into their CW and pulsed component signals. The pulsed component signals may be digitized by narrowband multibit analog-digital converters (ADC) while the CW component signals are digitized by high speed low latency mono-bit ADCs to determine frequency components (e.g., bandwidth information) and other spectrum information of the RF input signal.
