Microwave transmission device for satellite , tracking method of target area using the device , and control program

摘要

PROBLEM TO BE SOLVED: To enable a microwave transmission device to be mounted on a small earth orbiting satellite and also to make the orientation direction to be continuously variable.;SOLUTION: By a first antenna horn 3a, the target zone on the earth is irradiated with a first microwave S5a while the orientation direction is changed like arrows a and b accompanying with the movement of the artificial satellite through a parabola antenna 4. By a second antenna horn 3b, when the target zone is irradiated with the first microwave S5a by the first antenna horn 3a through the parabola antenna 4, a next target zone is oriented by irradiating with the second microwave S5b through the parabola antenna 4. When the irradiation with the first microwave S5a to the target zone is finished by the first antenna horn 3a through the parabola antenna 4, the next target zone oriented by the second antenna horn 3b is immediately irradiated with the first microwave S5a by the first antenna horn 3a.;COPYRIGHT: (C)2013,JPO&INPIT
