The invention provides a broadband wave-absorbing OSR secondary surface mirror and a preparation method thereof. The broadband wave-absorbing OSR secondary surface mirror comprises a protective layer, a reflecting layer, a base material and a resonance unit layer which are stacked, the reflection layer is a metal silver plating layer with reflection capability in visible light and near-infrared bands, the protection layer is a chromium-plated alloy plating layer, the resonance unit layer is an ITO hollow pattern, broadband wave absorption is realized through impedance matching and multimode resonance, and the resonance unit layer has light transmission capability in the visible light band. The wave-absorbing material is simple and reasonable in structure, light in additional weight and high in implementability, can be flexibly applied to the surface of a satellite structure, has a wide-frequency-band wave-absorbing function on the basis of not influencing the thermal control performance, and can effectively reduce the radar cross section of the satellite surface.
