Embodiment Construction
[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.
[0017] This embodiment provides a method for on-orbit joint calibration of multi-beam spaceborne laser altimeters. On the basis of setting up reference beams, the ground three-dimensional coordinates of the laser spots of each beam obtained in advance are taken as known data into the constructed The multi-beam spaceborne laser altimeter is in the on-orbit calibration model, so that the beam pointing and ranging calibration of the reference beam 1 to beam N can be performed. During specific implementation, automatic operation and processing can be realized through computer software technology.
[0018] Such as figure 1 As shown, the on-orbit joint calibration process of the multi-beam spaceborne laser altimeter includes the following steps:
