The invention discloses a light-operated microwave phased array radar system based on a pluggable transmit-receive assembly and a feedback control method. According to the technical scheme adopted bythe invention, photonic integrated chips with different functions are realized by using a plurality of material platforms; the plurality of chips are interconnected through an inter-optical-chip coupling technology to realize an all-optical integrated transmit-receive assembly, and meanwhile, a control electric chip and the optical chip assembly are packaged in the same tube shell by using a flipchip or wirebonding technology, and finally, the pluggable transmit-receive assembly and the light-operated phased array radar system formed by the pluggable transmit-receive assembly are obtained. Themicrowave phased array radar assembly provided by the invention is constructed based on the optical chips, has strong anti-electromagnetic interference capability, and improves the signal transmission capacity; delayers based on the optical chips have the same delay for microwave signals modulated on optical carriers at different frequencies, so that the problem of beam deflection is solved; gains of all the assemblies can be independently controlled, Gaussian distribution of array element gains can be achieved, and therefore, beam scanning with the high sidelobe rejection ratio is achieved.
Description
technical field [0001] The invention relates to microwave phased array radar technology, in particular to an optically controlled phased array radar system based on pluggable transceiver components and a control method thereof. Background technique [0002] With the rapid development of information technology, future warfare will develop in the direction of large-scale and three-dimensional warfare, and with the leapfrog improvement of satellite communication technology and artificial intelligence technology, the overall combat will move towards the integration of sea, land, air and space, intelligence and Development in the direction of multi-platform integration. And it will have the characteristics of ultra-long-distance, all-weather, fast, flexible and accurate, and highly developed information acquisition, control and use technologies will occupy an increasingly important position in future warfare. As the "clairvoyance" and "wind ear" in the war, the radar transmittin...
