Abstract

A photonic-assisted transceiver with wavelength reuse for distributed ultra-wideband (UWB) radar is proposed and demonstrated. The transceiver converts an input optical phase modulated signal into an optical UWB pulse train based on phase modulation to intensity modulation conversion using a fiber Bragg grating, and performs wavelength reuse by re-modulating the phase modulated optical signal via an intensity modulator. The transceiver is applied in a UWB ranging radar. A centimeter level accuracy is achieved.
