Polarímetro en banda W para aplicaciones de radioastronomía: diseño y simulación

Abstract

This contribution presents and analyzes a polarimeter scheme for radio astronomy applications in W-band. The scheme is based on a sub-harmonic mixer thus enabling the reduction of W-band hardware design. The receiver functionality is analyzed theoretically and the design of some subsystems such as the feed-horn, the polarizer and the orthomode transducer is shown in detail. Finally, the whole scheme is simulated in an ideal way and then realistic data files are introduced in order to check the receiver functionality and the expected performance.
