Ground detector for laser radar on-orbit calibration

The invention discloses a ground detector for on-orbit calibration of a laser radar, and relates to the field of satellite laser calibration, the ground detector for on-orbit calibration of the laser radar comprises an optical filter, the optical filter is a narrow-band optical filter, other sunlight and stray light are shielded except for the wavelength of 532 nm +/-delta lambda nm, delta lambda is the bandwidth of the optical filter, and the width of the optical filter is larger than that of the narrow-band optical filter. Compared with the prior art, the ground pulse laser detector has the advantages that the ground pulse laser detector is developed in a targeted mode according to the characteristics of micro energy, high frequency and low pulse width of ground pulse laser; the detector can provide data support for in-orbit calibration of beam pointing angles of emitted Gaofeng No. 7 02 satellites and other similar single-photon-system laser radars, realizes real-time ground verification of the beam pointi
