A phased array radar receiving device based on photon parameter sampling, comprising: a continuous light source, a first multi-channel coupling module, a phased array receiving module, a modulator array, a multi-channel optical delay array, and a second multi-channel coupling module , an optical sampling pulse source, a photon parameter sampling gate, an optical filter, a photoelectric converter, and an electrical acquisition module. The present invention combines optical true delay technology and photon parameter sampling technology, reduces the number of electro-optical / photoelectric conversions in microwave photon radar, thereby reducing system loss, and at the same time realizes large bandwidth and high-speed acquisition of signals, reducing the number of times at the traditional radar receiving end Increased system complexity and performance degradation caused by electrical frequency mixing and down-conversion.
Description
technical field [0001] The invention relates to microwave photon signals, in particular to a phased array radar receiving device based on photon parameter sampling. Background technique [0002] Phased array antenna systems are widely used in fields such as radar, communications, and electronic countermeasure systems, among which high-quality broadband tunable microwave signal sources, broadband radar baseband signal sources and phase-delayed beamforming networks are the core components of the system. Traditional electronically controlled phased array radars are limited by the "aperture effect" of phased array antennas, which limits their applications in the fields of radar operating bandwidth, high-resolution measurement, radar imaging, and spread-spectrum signals. [0003] With the development of microwave photonics technology and its extensive research in the field of radar, the limitation of aperture transit time in traditional phased array antennas can be effectively ov...
