Microwave/millimeter-wave photonics is playing a prominent role in overcoming the challenges of RF signal generation and processing. This evolving technology has many advantages, such as RF carrier stability and broad operating bandwidth, and is applicable to a wide range of civil and military ...
In this article, a photonics-based real-time high-range-resolution radar is proposed with optical generation and processing of broadband linear frequency modulation (LFM) signals. A broadband LFM signal is generated in the transmitter by photonic frequency quadrupling, and the received echo is de-...
In this work, a photonics-based wideband multi-format tunable radar jamming signal generator using a dual-polarization quadrature phase-shift keying (DP-QPSK) modulator is proposed. The received LFM signal, rectangular pulse train, and electrical comb spectrum signal are separately loaded into the DP...

A photonics-based integrated communication and radar system is proposed and demonstrated by encoding an amplitude shift keying (ASK) modulation signal onto an linear frequency modulated continuous wave (LFMCW) radar signal. In the experiment, communication rate of 100 Mbit/s is achieved and inverse ...
We propose and demonstrate a photonics-based coherent dual-band radar for super-resolution range profile in this paper. This radar cannot only generate coherent dual-band linear frequency modulated signals with large bandwidths, but also realize a paralleled coherent de-chirping processing to the ...
