APPARATUS FOR DETERMINING THE POLARIZATION OF A RADAR SIGNAL USING THE DOUBLE LINEAR POLARIZATION PROPERTY OF A SINGLE SINUOUS ANTENNA AND A HYBRID COUPLER AND A METHOD THEREOF

摘要

PURPOSE: An apparatus for determining the polarization of a radar signal and a method thereof are provided to receive a vertically polarized wave, a horizontally polarized wave, a left turn circular polarized wave, and a right turn circularly polarized wave.;CONSTITUTION: An apparatus for determining the polarization of a radar signal comprises a sinuous antenna(10), a divider(20), a hybrid coupler(30), and a polarization determining unit(40). The antenna receives the linear polarization of a radar signal which is received in real time. The divider branches off the linear polarization to first linear polarization and second linear polarization. A hybrid coupler changes the first polarization into circular polarization. A polarization determining unit distinguishes the polarization of the radar signal which is received in real time based on the second linear polarization and the circular polarization.;COPYRIGHT KIPO 2012
