<p>The present invention relates to a separation wall for a transmission/reception antenna isolation, which uses a serration structure so as to improve isolation between transmission/reception antennas in a radar system in which a transmission antenna is separated from a reception antenna, and a radar antenna system for a precipitation measurement using the same. According to the present invention, the radar antenna system comprises: a support frame (160); a transmission antenna (111) which is installed on one side of the support frame (160) and is inclined at a predetermined angle: a reception antenna (112) which is installed on the other side of the support frame (160) and is inclined at a predetermined angle; a separation wall which is installed on the support frame (160) between the transmission antenna (111) and the reception antenna (112); a transmission feed horn cover (150) which is disposed on a transmission side surface of an outer wall (110) of the separation wall; a transmission feed horn (311) which is disposed inside of the transmission feed horn cover (150); a reception feed horn cover (190) which is disposed on a reception side of the outer wall (110) of the separation wall; a reception feed horn (312) which is disposed inside the reception feed horn cover (190); a transmission unit box (411) which transmits a RF signal through the transmission feed horn (311); a reception unit box (412) which receives the RF signal through the reception feed horn (311); and a signal processing unit box (413) which is connected to the transmission box and the reception box and processes a transmission/reception signal.</p> |
