摘      要：The influence of thermal deformation on the performance of reflector antennas has become increasingly significant with the increasing aperture and working *** use of a thermal compensation database is an efficient method to compensate for the deformation caused by the non-uniform temperature ***,how to efficiently and accurately match and call the database remains as one of the tough challenges for the antenna thermal compensation system to achieve real time ***,this study proposes a data match and call method for the thermal compensation database of the reflector antenna,matching the database from three aspects:the overall rms match of temperature data,the similarity area match of each data sample,and the key area match of key structural *** validation of this method is demonstrated in an *** difference between the pointing adjustment amount calculated by the matched data and the collected data was found to be less than 1,which satisfied the requirements of practical engineering,thus achieving real-time thermal compensation of the antenna.
