Full-spectrum covering ultra wideband all photonics-based radar system
A full-spectrum covering ultra wideband full-photonics based radar system comprising a signal transmitter, a transceiver module, and a signal receiver. The signal transmitter comprises a mode-locked laser, a first dispersion module, a first optical coupler, a second optical coupler, a first optical filter, a second dispersion module, a second optical filter, a first adjustable time delay module, a third optical coupler, an optical amplifier, and a first photodetector; the transceiver module comprises a band selector, a first electrical amplifier array, a T/R component array, an antenna array, and a second electrical amplifier array; the signal receiver comprises a third optical filter, a second adjustable time delay module, an electro-optical modulator, a third dispersion module, a second photodetector, an analog-digital conversion module, and a signal processing module. The system has continuous tunability for center frequency, bandwidth, and time width of the wideband signal with high coherence and ranging accuracy.
