Analysis of Test Distance and Truncation Angle of the Two-dimension Phased Array Radar Antenna

Abstract

The plane near-field test is carried out by using the two-dimension phased array radar antenna at different truncation angles and distances of the probe. The measured results are given, and the influence of the angle of truncation and the distance on the measurement results are analyzed. According to the results, the near-field test errors corresponding to the antenna parameters can be estimated, and the parameters of the near-field test can be determined.
