Embodiment Construction
[0077] Such as figure 1 As shown, the real-time method for maintaining the ideal shape of the active main reflector antenna based on the reference point includes the following steps:
[0078] Step 1, installing laser measuring equipment and storing relevant data of the sub-reflector.
[0079] Such as figure 2 As shown, install the laser ranging goniometer system on the back of the sub-reflecting surface, reserve a hole of appropriate size at the apex of the sub-reflecting surface, move the laser probe to the hole position at the apex of the sub-reflecting surface, and assume that the measurement coordinate system and the sub-surface coordinate system coincidence, denoted as O s -x s the y s z s , where O s is the origin of the coordinates, located at the apex of the sub-reflector; calibrate two sub-reflector pose orientation points on the sub-reflector: O s dot and o s -z s A point D on the axis, point D is at O s -x s the y s z s The coordinates in the coordinat...
