Embodiment Construction
[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the embodiments of the present invention are not limited thereto.
[0039] refer to figure 1 , a phased array beam-to-star tracking system based on broadband frequency hopping signals, comprising: a receiving subarray unit 10, a subarray delay compensation unit 20, a beamforming network 30, a frequency hopping de-hopping unit 40, a beam tracking unit 50, Beam control unit 60 and combined inertial navigation 70;
[0040] The receiving sub-array unit 10 includes a plurality of receiving sub-arrays 1-M, which are respectively used to adjust the beam pointing under the control of the beam control unit 60, and receive frequency-hopping incoming waves, and undergo phase shifting, attenuation and combining, completing the first-stage beamforming, and outputting the first-stage beamforming signal to the subarray delay compensation unit 20;
