Abstract

Abstract: On the basis of the principle of SAR(synthetic aperture radar) system, significance of SAR antenna's phase center is analyzed and two parameters are summed up: LMS location of aperture-plane phase center and relative inserted phase shift. By using the GO(geometrical optics) principle and least square estimation, the measurement method for the two parameters is presented and verified by a two-aperture phased array antenna.

Key words: synthetic aperture radar(SAR), phase center, least square estimation
