The chief principle is based on the front intersection measurement aided by two electric theodolite . the laser emitter casts light, spots on the antenna surface and gets the 3d coordinates of the sample data . then, the surface precision of the antenna can be obtained by corresponding data processing 雷達(dá)天線檢測原理是由激光目標(biāo)發(fā)生器投射光點(diǎn),兩臺(tái)電子經(jīng)緯儀前方交會(huì)測量,得到采樣點(diǎn)的三維坐標(biāo)值,再進(jìn)行相應(yīng)的數(shù)據(jù)處理,最終對天線面的變形情況和蒙皮表面加工誤差作出評價(jià)。
