| Abstract: | Based on the special requirements of multi-beam performance test and high-precise ranging performance calibration for the digital multi-beam antenna and its operation principle,this paper analyzes two calibration and test methods respectively based on far-field and near-field.The correction methods for beam directivity,level and phase center of the digital multi-beam antenna are proposed,and the test demonstration is performed with practical system.The result shows that the method can effectively implement calibration and test for digital multi-beam antenna system and improve the measurement accuracy,and has higher practical value. |
