| Abstract: | The electrical performance test method for airborne phased array radome differs from the traditional test methods. How to scan the phased array antenna and control the beam former are researched in this paper. The installation of array phased antenna in null-seeking system and the aligment between receiving and sending axis are determined. The function and precision of the null-seeking system meet the test requirements for phased array antenna is elaborated. The measurement of a radome of X band phased array antenna proves that the null-seeking system can be applied for new type of fighter airplane radome researching and development. |
| Keywords: | phased array antenna radome null-seeking method null-seeking system beam former |
