The invention discloses a dual-band reflective two-dimensional scanning search and tracking platform, which comprises a pedestal, a U frame and a mirror, wherein a pitching shaft is arranged on the pedestal; one end of the pitching shaft is connected with a pitching motor and the other end is connected with the U frame; the U frame is provided with an azimuth shaft whose axis is vertical and intersected with the axis of the pitching shaft and an azimuth motor which drives the azimuth shaft; the mirror is fixedly arranged at the middle part of the azimuth shaft; and the rotating axis of the azimuth shaft is located in a plane of a reflecting surface of the mirror. The load is light, the moment of inertia is little, the scanning mode is flexible, a precision driving control technology is adopted, a continuous or stepping scanning mode is selected, quick and high-precision control on system boresight pointing can be realized, technical verification on space moving target searching, capturing and tracking by a low earth orbit satellite optical load can be realized, a small-view field optical load can be ensured to acquire a larger searching view field, the captured target can be aimed and tracked precisely, and influences on the satellite stability by a rotation movement can be reduced as much as possible.
