Embodiment Construction
[0018] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0019] figure 1 The overall system structure diagram of the microwave photonic link based on full-spectrum utilization and post-compensation technology is described in , where S101 is the input microwave signal, which is modulated to S103 by the photoelectric phase modulator S102: the light provided by the continuous optical laser on the carrier. The modulated optical-carrying microwave signal passes through the second photoelectric phase modulator S104, which is driven by the microwave local oscillator represented by S105, and converts the optical-carrying microwave signal from high frequency to the difference frequency between S101 and S105, thereby realizing The down conversion is turned on. The down-converted signal carried by the light is used by the full-spectrum utilization module to utilize both the transmission spectrum and the reflection spec...
