Polarization Property of Scanning Slot Phased Array

摘要：

There are three typical definition of cross polarization in mechanical scanning antenna,and they are not completely proper for electronic scanning phased array antenna.We use wave-guide slot phased array antenna in this paper to study the changing of polarization property as beam scans in wide airspace.Simulation shows that the property of lobe and polarization changes not much in the case of small azimuth and elevation scanning angle.However,there is dramatic increase of cross polarization component in main lobe in the case of large scanning angle.We can use this characteristic to measure polarization property of target in phased array radar searching stage.
