Embodiment Construction
[0044] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0045]In order to facilitate understanding of the present invention, Fig. 2 shows the schematic diagram of the principle of the compensation method proposed by the present invention, the direction S in the figure represents the beam scanning direction, the angle Δβ is the included angle along the scanning direction between the receiving beam and the transmitting antenna beam, and the angle Δθ Indicates the scanning offset of the antenna beam pointing, the number 21 indicates the ground footprint of the receiving antenna at the time of transmission, the number 22 indicates the ground footprint of the transmitting antenna at the time of transmission, and the number 23 indicates the ground footprint of the receiving antenna at the time of reception. when
[0046] When Δβ=Δθ (7), the offset loss caused by beam scanning can be fully compensated: when...
