The application discloses a kind of based on
best fitting accuracy reflector antenna
actuator layout method, comprising: obtaining the average of reflector deformation under the condition of looking up and pointing flat, and the deformation of reflector at different
pitch angles is pre-adjusted;The pre-adjusted deformation reflector is obtained by translation and rotation to best approximate ideal reflector, obtain the
maximum error distribution range, determine the
layout scheme of
actuator corresponding to reflector;Determine the adjustment
target surface when reflector antenna is in the condition of looking up, obtain the adjustment amount of
actuator when reflector antenna is in the condition of looking up;Obtain the adjustment accuracy when reflector antenna is in the condition of looking up;Update the preset error threshold value, and correspondingly update adjustment accuracy, until the curve of adjustment accuracy under all conditions with preset error threshold value is obtained;According to the adjustment accuracy of
engineering requirement, the corresponding error threshold value is obtained on the curve, and the
layout scheme of actuator is obtained.The application can obtain the best actuator layout scheme.
