Feasibility analysis of space-based active and passive fusion detection

To achieve space-based positioning and imaging detection of space debris under complex lighting and large relative motion conditions, in response to the high relative speed, high-resolution imaging, precision ranging, and positioning requirements faced by space-based optical payloads, this paper proposes a new system with active and passive fusion detection. It utilizes the advantages of multiple bands (visible, infrared, and laser), combines wavefront sensing, the control of composite axis, and super-resolution imaging technologies, and has the characteristics of high reliable target acquisition, high-precision tracking, ranging, and high-resolution imaging in complex scenes. The simulation analysis results show that the capture distance for targets with a radiance of 10W/sr is better than 100 kilometers, and for the targets at a relative motion speed of 6km/s, sub meter level imaging and ranging can be achieved. It provides reference for the space-based optical payload.
