Abstract

Abstract: A method of calibration method for radar antenna electromechanical axis consistency is introduced. The aim is to get transformation of structure coordinate and wave coordinate.Fixing a cubic prism on the face of radar antenna is to transform coordinate.To solve the problem of oversize error in single measure，it measures twice in lab and microwave anechoic chamber, and calibrates transformation of structure coordinate and wave coordinate with cubic prism coordinate. Through date processing and uncertainty eraluation, the electromechanical axis consistency is varified.

Key words: Radar antenna, Coordinate transformation, Cubic prism, Measurement method
