RT Journal Article T1 A New Automatic System for Angular Measurement and Calibration in Radiometric Instruments A1 Andújar Márquez, José Manuel A1 Martínez Bohórquez, Miguel Ángel A1 Aguilar Nieto, Francisco José A1 Medina García, Jonathan AB This paper puts forward the design, construction and testing of a new automatic system for angular-response measurement and calibration in radiometric instruments. Its main characteristics include precision, speed, resolution, noise immunity, easy programming and operation. The developed system calculates the cosine error of the radiometer under test by means of a virtual instrument, from the measures it takes and through a mathematical procedure, thus allowing correcting the radiometer with the aim of preventing cosine error in its measurements.
