The BJ-3A satellite and the BJ-3B satellite are currently of the most imaging modes of high-resolution optical remote sensing satellite in China. Including the conventional multiple targets, stereo, tri-stereo, stripe mapping over large area, corridor acquisition modes in single pass, the BJ-3A/B satellites have the creative capacity of north-south direction active forward and reverse push-broom multiple contiguous stripes imaging mode. This article focuses on the characteristics of active forward and reverse push-broom imaging over large area with north-south stripes, a ground preprocessing flow of camera gear adjustment according to land cover and imaging mode, line during time normalization of reverse push-broom image, and high-order polynomial fitting and extrapolation for attitude parameters are designed to produce standard sensor corrected image product for active forward and reverse push-broom imaging mode. Taking the plane accuracy measurement of BJ-3B north-south 5-stripe forward and reverse push-broom digital orthophoto maps as an example, the sub-0.5m forward push-broom image can meet 1∶2000 scale plane accuracy requirement, and the sub-0.5m reverse push-broom image can meet 1∶5000 scale plane accuracy requirement.
