| Abstract | 本发明公开了一种基于指向调整的天线热变形补偿数据库匹配调用方法，包括：根据采集温度数据和天线指向调整量，得到热变形补偿数据库；传感器采集温度数据，计算采集温度数据组的均方根误差RMS值；采集温度数据组RMS与数据库存储温度数据组RMS相匹配，计算相似性匹配区域并进行匹配，计算关键性匹配区域并进行匹配，比较匹配成功数据组的相似匹配率，找出唯一匹配数据组，得到反射面天线指向调整量，判断指向调整量是否用于指向调整，在数据库中添加新采集的温度分布。本发明根据实时采集的温度数据，通过匹配数据的RMS值、相似性区域、关键性区域对数据库进行匹配调用，逐层缩小匹配范围，完成反射面指向调整补偿，保证补偿的准确及效果。 |
| Other Abstract | The invention discloses a method of matching and invoking of an antenna thermal deformation compensation database based on orientation adjustment. The method comprises the following steps: based on the acquired temperature data and antenna orientation adjustment amount, obtaining a thermal deformation compensation database; a sensor acquiring temperature data, calculating a root mean square error RMS value of a temperature data acquiring group; the RMS of the temperature data acquiring group matching the RMS of a storage temperature data group in the database, calculating a similarity matching area and performing matching, calculating a critical matching area and performing matching, comparing similarity matching rates of data groups that have successful matching, finding the only matching data group, obtaining antenna orientation adjustment amount of a plane of reflection, determining whether the orientation adjustment amount is used for orientation adjustment, adding the newly acquired temperature distribution to the database. According to the invention, based on the real-time acquired temperature data, the method performs matching and invoking on the database through the RMS value for matching data, similarity area, and critical area, reduces matching scope gradually, thus completing orientation adjustment compensation of the plane of reflection and guaranteeing compensation accuracy and effect. |
