| Abstract: |
| The method of Subreflector Feed Angle Calibration is the important
approach of towerless angle calibration. For solving the problem that it is dif
ficult to precisely locate the couplingaperture in the subreflector feedback m
ethod of angle calibration, a new towerless angle calibration method
is presented under the condition that the subreflector of antenna and the feedb
ack horn are not symmetrical. The theory and steps of the method are introduce
d particularly. Finally，the correctness and the efficiency of the method are va
lidated by experiments. |
