Remote sensing calibration comprehensive method and calibration equipment vehicle

Abstract

The invention relates to a remote sensing calibration comprehensive method and a calibration equipment vehicle. According to the invention, calibration equipment is integrated into a vehicle-mounted system; a novel mobile target is established to perform the far-field quick calibration and the optical spectrum and radiation resolution combined calibration; the differences on aspects of optical spectrum, radiation and geometry between a hard target and a conventional soft target on a remote-sensing image are analyzed through comparison of different time phases, so as to establish a performance degradation compensation model for the soft target to realize correction calibration; an information receiving device equipped on a vehicle body can receive videos of aircrafts in the air and acquired ground data so as to realize four-resolution combined calibration of geometric distortion and time phase data and the optical spectrum and radiation data of the vehicle body based on wireless transmission; the status of unknown remote sensing calibration results and delayed data processing in the past can be changed through analysis and processing by high-performance computers; a set of ground experiment remote control and flight information feedback communication link is established, and the difficult situation of difficulty in information interaction among the air, the ground and command center, and out-field workstations is changed.
