title = "High-stable photonics-based frequency-quadrupled LFM signal generation for radar applications",
abstract = "A high-stable photonics-based linearly frequency-modulated (LFM) signal generation approach for radar applications is proposed and experimentally demonstrated. A broadband LFM signal is generated by a photonic frequency quadrupler consisting of a Mach-Zehnder modulator and a fiber Bragg grating (FBG)-based optical notch filter. The stability of the generated signal is improved by using modulator bias control, laser wavelength control, and FBG temperature control. An experiment is performed. A Ka-band LFM signal with an instantaneous bandwidth of 4 GHz is generated. Meanwhile, inverse synthetic aperture radar (ISAR) imaging and target distance measurement are implemented by using a generated 1-GHz bandwidth LFM signal. The LFM signal remains stable during the four-hour experiment.",
