A NEW METHOD OF COLLIMATION OF ACTIVE ARRAY ANTENNA BY SIMPLIFIED NEAR FIELD SCAN

摘要

"A METHOD OF COLLIMATION OF ACTIVE ARRAY ANTENNA" This invention relates to a method of collimation of active array antenna. A probe is moved along a lien around which the elements of active antenna are located and activating each antenna element separately and sequentially for characterizing, receiving and transmitting segments. The data received are processed to obtain maximum gin and maximum phase value, which are compared with a reference data to evaluate gain and phase coefficient. Each active array is then coUimated on the basis of said correction coefficient.
