A fiber-distributed bistatic ultra-wideband (UWB) radar based on optical time division multiplexing (OTDM) is proposed and demonstrated. The proposed radar consists of a central office (CO) and two spatially separated transceivers. OTDM technology is implemented by inserting a certain length of optical fiber between the two radar transceivers, so the UWB pulses received by different transceivers can...
A fiber-distributed multistatic ultra-wideband (UWB) radar is proposed and demonstrated. The proposed radar includes a central office (CO), two transmitters and a receiver which are connected by optical fibers. The UWB pulses generated by the two transmitters are designed to have opposite polarities using the complementary transmission and reflection responses of an FBG, so that it is easy to identify...
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...
A fiber-distributed Ultra-wideband (UWB) noise radar is proposed and demonstrated, in which a nonlinear electro-optic oscillator with inbuilt UWB band-pass filter is applied as signal source to provide the chaotic-UWB signals with ideal spectral shape. In order to improve the compatibility but reduce the cost and complexity, the colorless base station is implemented for the first time by utilizing...
